How the New Catalist Report on 2024 Compares to the Exit Polls By Kyle Kondik and J. Miles Coleman

KEY POINTS FROM THIS ARTICLE

– A new report from the Democratic data firm Catalist provides a fresh look at the 2024 presidential election results.

– There are key differences among the two Election Night exit polls, from Edison Research and from VoteCast, and the Catalist report, but they by and large tell a similar story about the election.

– All three sources show Trump making big improvements compared to 2020 among young and nonwhite voters.

Notes on the State of the Senate: The Post-Kemp Battlefield By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— Republicans missed out on a top recruiting target earlier this week, as Gov. Brian Kemp (R-GA) decided not to challenge Sen. Jon Ossoff (D-GA).

— Georgia remains a Toss-up in our ratings even as Ossoff’s reelection path got clearer.

— Another place where Democrats are playing defense, Michigan, remains a Toss-up, while a couple of other open Democratic seats in Democratic-leaning states, Minnesota and New Hampshire, are developing better for Democrats than Republicans.

— While there have already been many key developments in the race for the Senate in 2026, history shows that key candidate decisions may still be months away in some places.

— Republicans remain favored to retain control of the Senate in 2026, and we are not changing any ratings in this update.

The Governors, Part Two: Familiar Battlegrounds Dot 2026 Map, but Watch for Upsets in Open Seats By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— Many of 2024’s top presidential battlegrounds will feature high-profile gubernatorial elections in 2026.

— Arizona and Michigan start as the only two Toss-ups in our initial ratings.

— Be on the lookout for upsets thanks to the high number of open seats, perhaps coming from the long list of races that start rated as Likely for one side or the other.

The House: Democrats Favored on What Starts as a Small Battlefield By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— History suggested Democrats would be favored to flip the House in 2026 as soon as Donald Trump clinched the presidency in 2024.

— Little that’s happened over the last several months calls into question that initial, gut-level assessment. Democrats should flip the House next year, and we favor them to do so. Republicans do have a couple of factors working in their favor, though, that could help them as they seek to defy history.

— Our initial House ratings reflect a small House map, with Democrats narrowly ahead 209-207 in the seats that at least lean to one party or the other, with 19 Toss-ups.

Three Things That Usually Happen in Midterms By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— There are at least three fairly consistent things that we see in midterms compared to presidential elections.

— The turnout of eligible voters in midterms is consistently lower than the turnout in the most recent presidential election.

— Midterm electorates are typically older, whiter, and more educated than presidential electorates.

— The non-presidential party usually wins a higher share of the two-party House vote in the midterm than that party did in the preceding presidential election.

Lessons from History: House Incumbents from the Non-Presidential Party Rarely Lose Reelection in Midterms By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— The non-presidential party often picks up House seats in midterms, and as a part of it, that party’s incumbents rarely lose in midterms.

— Over 13 general election midterms held during the last half-century, just an average of 3 non-presidential party House members have lost per midterm.

— Redistricting as well as special election winners losing their subsequent general election inflate that total. Otherwise, a variety of other factors—including scandal, strong challengers, political circumstances, and more—contributed to these relatively rare losses.

Trump’s Approval: Still Positive, but Overperformance with Democratic-Leaning Groups May Be Hard to Maintain By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— As his second term enters its second month, Donald Trump retains a positive approval rating in polling averages.

— However, his numbers in polling averages are weaker now than a few weeks ago, driven more by an increase in disapproval than a decline in approval.

— Compared to his 2024 performance with certain demographic groups based on the national exit poll, Trump is overperforming the most with some typically Democratic constituencies.

Our Initial Senate Ratings: Republicans Start as Strong Favorites to Hold Majority By Kyle Kondik and J. Miles Coleman

KEY POINTS FROM THIS ARTICLE

— While Republicans, who will be defending 22 of the 35 Senate seats up in 2026, may have the political environment working against them next year, they are still favored to retain the chamber.

— Part of the reason for this is that Democrats hold two of our three initial Toss-up races, Georgia and Michigan, while GOP-held North Carolina will likely see another hotly-contested Senate race.

— We are giving Maine’s Susan Collins (R) a degree of deference by starting her race as Leans Republican, although as the only Republican representing a Kamala Harris-won state, it is hard to see Democrats getting close to a majority without her seat.

— If Democrats were to be on track to regain the Senate by the end of the decade, they would almost certainly have to come out of the 2026 cycle with a net gain of seats.

The 2024 Crossover House Seats: Overall Number Remains Low with Few Harris-District Republicans By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— Just 16 districts voted for one party for president and the other for House, which is the same historically-low total as 2020.

— But there are 13 Democrats in Donald Trump-won districts compared to just 3 Republicans in Kamala Harris-won districts.

How the Other Half Votes: The Big Counties Versus the Rest of the Country in 2024 By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— While the nation has more than 3,100 counties, just about 150 of them cast roughly half of all presidential votes.

— In the Trump era, the gap between the biggest counties and the rest of the country is larger than it was previously, although the overall difference contracted slightly in both 2020 and then 2024 after an initial large widening in 2016.

— In improving his margin in the national popular vote by about 6 points from 2020, Donald Trump ran further ahead of his 2020 margin in the nation’s most vote-rich counties than he did in the rest of the country.

The End of the Line for Red State Senate Democrats By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— As part of capturing the Senate this year, Republicans knocked out the final remaining Democratic senators from a group of 20 states that have consistently voted Republican for president since at least the 2000 election.

— A quarter-century ago, Democrats held nearly a third of the Senate seats from these 20 states. But that tally was down to just 2 leading into this election, and Republican victories in Montana and West Virginia reduced it to 0.

— Additionally, 5 other states backed a Democratic presidential candidate at least once this century but voted for Donald Trump in all 3 of his elections. Republicans now hold all of the Senate seats in these states as well.

— In total, these 25 states hold half the Senate seats. Realistically, Democrats can’t win future Senate majorities without making at least some inroads back into this now fully Republican bloc of states.

The 2024 Senate Undervote: Not High By Historical Standards By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— After the election, many took note of some seemingly unusual patterns in the presidential and Senate voting. Some winning Democrats in states that voted for Donald Trump, for instance, received fewer total votes than Kamala Harris, but still won while Harris lost.

— Some voters likely cast votes just in the presidential race, meaning that there were fewer votes cast in a state’s Senate contest compared to its presidential contest.

— However, there is nothing unusual about this compared to recent history. Senate races almost always have fewer votes cast than presidential races in presidential years.

— In fact, the average size of the Senate “undervote” this year was smaller than many other recent cycles.

— The third party vote was generally larger in key Senate races than in the presidential race, which likely also contributed to the outcomes in certain states. But a higher third-party vote for Senate is also not unusual—it was a feature of some of 2020’s closest Senate races, too.

Rating Changes: Pushing House Toss-ups, Nebraska Senate to Leans Republican By Kyle Kondik and J. Miles Coleman

KEY POINTS FROM THIS ARTICLE

— We are pushing a few House Toss-ups out of that category this week, leaving revised ratings that show 212 House seats at least leaning Republican, 209 at least leaning Democratic, and 14 Toss-ups.

— Just like in the presidential race, there’s still no favorite in the House.

— We also are moving Sen. Deb Fischer’s (R-NE) race from Likely Republican to Leans Republican, as the Republican cavalry has had to ride in to help her in her contest against independent Dan Osborn.

Five House Rating Changes as Overall Battle for Majority Remains Tight By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— We are changing 5 House ratings this week, although that does not change our overall arithmetic in the House. We continue to view the race for the chamber as effectively a 50-50 proposition.

— The real playing field may be smaller than what we saw in the 2022 election cycle, if current outside spending is any indication.

— Beyond our rating changes, we have some observations about key races across the competitive map, including in Iowa, Maine, Michigan, Nebraska, North Carolina, and Virginia.

Polling Error in 2016-2020: Look Out for Wisconsin By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— Swing state polls show an incredibly close race in our 7 Toss-up presidential states right now.

— Final polling did generally overstate Democrats in both the 2016 and 2020 elections in these states, with Wisconsin standing out. Keep that in mind as polling shows Kamala Harris holding up a little bit better in the Badger State than elsewhere.

— If polls are understating Donald Trump again, he of course is in a great position to win given how competitive he already is in the core swing states. But there are good reasons to believe that he is not being overstated this time.

Harris’s VP Choice: Her Options, and the Possible Home State Effects By Kyle Kondik and J. Miles Coleman

KEY POINTS FROM THIS ARTICLE

— Because of the unprecedented nature of the 2024 campaign, Vice President Kamala Harris, who stepped up to lead the Democratic ticket less than two weeks ago, has had an unusually abbreviated window in which to vet her own vice presidential prospects.

— The leading contenders to join Harris on the ticket are Gov. Josh Shapiro (D-PA) and Sen. Mark Kelly (D-AZ), although we are watching several other names.

— If Harris picks a running mate from a true swing state (like Arizona or Pennsylvania), it would be unusual, at least considering recent history, as most recent picks have not come from states at the center of the electoral map.

— Research is mixed on the home state bonus afforded by running mates; if any effect does exist, it is likely small—although just a small effect could be decisive in a key state.

Electoral College Rating Changes: Half-Dozen Moves Toward Republicans in What Remains a Toss-up Race By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— We are making six Electoral College rating changes this week, all in favor of Republicans.

— However, we don’t really see a clear favorite in a presidential race with many confounding factors.

— We consider Michigan, Pennsylvania, and Wisconsin to all be must-wins for the Democrats. While one can hypothetically come up with paths to 270 electoral votes for Democrats without them, we don’t find those paths to be compelling.

— Sen. Bob Casey (D-PA) remains a favorite in our ratings, but our shift of Pennsylvania to Toss-up in the presidential race prompts a concurrent change in his race, from Likely to Leans Democratic.

President vs. Senate: What to Watch in the Polls, and What History Suggests By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— A persistent finding in swing state polls is that Democrats are doing better in Senate races than Joe Biden is doing in the presidential race.

— At the topline, 2016 and 2020 produced hardly any split presidential and Senate results, suggesting that perhaps the presidential and Senate polling should converge.

— However, even in those years, there still was variation from state to state between the presidential and Senate margins.

— Focusing on the Senate races in the presidential swing states distracts from the races that will truly decide the Senate majority: red state seats with Democratic incumbents, Montana and Ohio.

An Electoral College Time Capsule By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— The six presidential elections held during the 25-year history of the Center for Politics were often close, although most states voted predictably.

— As part of a time capsule we are putting together to be opened at the center’s 50th anniversary in 2049, we are asking our future students to consider what has changed and what has stayed the same.

— Had we done the same exercise when the center was founded 25 years ago, we would have seen an Electoral College alignment from 1976-1996 that looked a lot different than what we’ve become familiar with this century.

Seniors for Biden? Looking Into the Polls Among Another Key Subgroup By Kyle Kondik

KEY POINTS FROM THIS ARTICLE

— Horse race presidential polling has shown some significant weaknesses for President Biden among at least a couple of key subgroups: young people and Black voters.

— However, some polls have also shown Biden doing unusually well among senior citizens.

— The oldest voters have generally voted to the right of the national vote in recent cycles, and that is probably what we should expect in 2024 as well, despite these polls.
