The latest polling data shows that Tea Party members and conservative evangelicals came out in force at the ballot box.
Polls show that 29 percent of voters identified themselves as evangelicals. The pollster Public Opinion Strategies says that made them the largest single group of the election. Seventy-eight percent of them voted Republican.
Fifty-two percent of those who identified themselves as part of the Tea Party also consider themselves conservative evangelicals.
"The socially conservative faith-based vote was the fuel and engine of the biggest midterm victory in our history," the Faith and Freedom Coalition's Ralph Reed said on Wednesday. Reed's group commissioned the post-election survey data.
Polls also show that a bloc of religious voters who usually vote for the Democrats switched sides in this election.
Fifty-four percent of Catholics voted for Republican candidates.
