About 4 in 10 voters this year identified as conservative, and approximately 9 in 10 of those in this group backed Republican candidates for Congress, according to both early network exit polling and preliminary voter polling from AP VoteCast. Conversely, roughly 9 in 10
liberal voters (who made up about a quarter of voters) supported Democratic candidates for the U.S. House. Among the almost 4 in 10 voters who identified as moderate, GOP candidates held a lead in both polls.
