Predictions for tomorrow's results

From Scott Rasmussen:

tomorrow Republicans will send more Republicans to Congress than at any time in the past 80 years. . . . Central to the Democrats' electoral woes was the debate on health-care reform. From the moment in May 2009 when the Congressional Budget Office announced that the president's plan would cost a trillion dollars, most voters opposed it. Today 53% want to repeal it. Opposition was always more intense than support, and opposition was especially high among senior citizens, who vote in high numbers in midterm elections.

Gallup

Gallup models the number of seats a party will control based on that party's share of the national two-party vote for the House of Representatives, using historical voting data in midterm elections from 1946 to 2006. The model takes into account the majority party in Congress entering the elections.

Gallup's historical model suggests that a party needs at least a two-point advantage in the national House vote to win a majority of the 435 seats. The Republicans' current likely voter margin suggests that this scenario is highly probable, making the question of interest this election not whether the GOP will win the majority, but by how much. Taking Gallup's final survey's margin of error into account, the historical model predicts that the Republicans could gain anywhere from 60 seats on up, with gains well beyond that possible.

It should be noted, however, that this year's 15-point gap in favor of the Republican candidates among likely voters is unprecedented in Gallup polling and could result in the largest Republican margin in House voting in several generations. This means that seat projections have moved into uncharted territory, in which past relationships between the national two-party vote and the number of seats won may not be maintained.

Additionally, efforts by state legislatures in recent years have attempted to insulate incumbent members of Congress from strong partisan tides such as are in force this year. Congressional district lines have been drawn to make them safe for specific parties, which may reduce the impact of national trends on election outcomes. . . .
