Republicans trail Democrats by 10 points on a generic House ballot, according to a Quinnipiac University poll out Thursday.

According to the survey, 50 percent of respondents said they want to see Democrats win control of the House, compared with 40 percent who want the GOP to keep control of the chamber.

But the poll also found a major divide along party lines, with 92 percent of Republicans backing their party and 93 percent of Democrats supporting theirs.

Another 10 percent of respondents said they either didn't know or declined to answer.

While Democrats hold a sizable lead over Republicans in the poll, it marks a slight boost for the GOP after a Quinnipiac poll earlier this month found a 14-point lead for Democrats on a generic ballot.
