Election 2010: Senate Balance Of Power

Senate Balance of Power: Dems 48 GOP 45 Toss-Ups 7

Monday, November 01, 2010

New polling in Connecticut has now moved that senate race from Solid Democrat to Leans Democrat in the Rasmussen Reports Election 2010 Balance of Power rankings.

Recent polling in New Hampshire has now moved that senate race from Leans Republican to Solid Republican.

Current projections suggest that the Democrats would hold 48 seats after Election Day while the Republicans would hold 45. Seven states are in the Toss-Up category (California, Colorado, Illinois, Nevada, Pennsylvania, Washington, and West Virginia). All seven Toss-Ups are seats currently held by Democrats.

Republicans have the edge in three Democratic-held Senate seats--Arkansas, Indiana, and North Dakota.

At the moment, no Republican-held seats appear headed for the Democratic column.

The state results and overall projections will be updated whenever new polling data justifies a change (to learn how Rasmussen Reports determines its Balance of Power rankings, click here).

In the table below, the states marked in red currently have a Republican senator. Those in blue currently have a Democratic senator.
