Americans Are Politically Divided and Our Feelings Toward the Parties Show It

How politically divided are ordinary Americans? The recent release of a report on polarization in public opinion by the Pew Research Center has reignited a debate among journalists and academics about the depth of the divisions between supporters of the two major parties. One of the key findings of the report is that supporters of the two parties hold increasingly negative feelings toward the opposing party and its leaders. While some scholars like Morris Fiorina of Stanford University have disputed the significance of these findings, an examination of evidence from the American National Election Studies provides strong support for the conclusions of the Pew study.

The ANES data make it possible to examine trends in feelings toward the Democratic and Republican parties over a fairly long period of time. Since 1978, the ANES has been asking national samples of American adults in every presidential election year and most midterm election years to rate both parties on a feeling thermometer scale. The scale ranges from zero degrees to 100 degrees with zero the most negative rating, 100 the most positive rating, and 50 a neutral rating. Ratings above 50 degrees are considered positive, while ratings below 50 degrees are considered negative.

Figure 1 displays the trends in the average ratings by voters of the Democratic and Republican parties on the feeling thermometer scale since the late 1970s. The results show that since the 1980s, there has been a clear decline in the average ratings of both parties. Since that time the average rating of the Democratic Party has fallen from the low 60s to the low 50s, while the average rating of the Republican Party has fallen from the upper 50s to the mid 40s. In fact, both parties received their lowest ratings ever in 2012.

Both parties are less popular today than they were 30 or 40 years ago, but that’s almost entirely due to a decline in ratings of the opposing party by Democratic and Republican identifiers. Figure 2 displays the trends in average ratings by voters identifying with a party — including independents leaning toward a party — of their own party and the opposing party. These results show that voters’ ratings of their own party have changed very little and remain quite positive. On average, voters continue to give their own party an average rating in the low 70s. In sharp contrast, ratings of the opposing party have declined substantially, falling from the upper-40s during the late 1970s and 1980s to the mid 20s in 2012. As a result, Americans, on average, rate their own party much more positively than the opposing party.

Americans’ feelings toward the Democratic and Republican parties are much more polarized today than 20 or 30 years ago. The data in Table 1 show that between the late 1970s and 2012, there was a dramatic increase in the proportion of Americans with a positive opinion of one party and a negative opinion of the other party. Over this time period, the proportion of Americans with such polarized opinions nearly doubled, going from 33% to 65%. There was an equally dramatic decline in the proportion of Americans with favorable opinions of both parties. During the late 1970s, more than a third of Americans had a positive opinion of both parties. By 2012, only 7% of Americans had a positive opinion of both parties. However, the proportion of Americans disliking both parties only increased slightly during this time period, going from 3% in the late 1970s to 8% in 2012.

The results displayed in Table 2 show that the increase in polarized opinions of the parties affected both Democratic and Republican identifiers. Between the late 1970s and 2012, the proportion of Democrats with a positive opinion of the Democratic Party and a negative opinion of the Republican Party increased from 32% to 71%, while the proportion of Republicans with a positive opinion of the Republican Party and a negative opinion of the Democratic Party increased from 39% to 65%.

Conclusions

Data from the American National Election Studies show that since the late 1970s, opinions of both major parties have become somewhat more negative. However, this is due almost entirely to the increasingly negative feelings that both Democratic and Republican identifiers, including independent leaners, hold toward the opposing party.

Feelings toward the parties are much more polarized today than they were in the late 1970s and 1980s, with far more voters holding positive feelings toward their own party and negative feelings toward the opposing party. This growing divide in voters’ feelings toward the parties has contributed to increased party loyalty and straight-ticket voting in elections. Voters may not like their own party any better today than in the past, but they dislike the opposing party much more than in the past and are less willing to consider voting for its candidates.
