A new poll shows voter frustration toward Republicans has significantly waned in recent weeks, with the GOP negating a 9 percentage-point disadvantage in generic polling and now running even with Democrats.

If congressional elections were held today, 39 percent of voters would cast ballots for Republicans -- the same percentage who would pick a Democrat, a Quinnipiac University poll says.

A Quinnipiac poll from Oct. 1 showed Democrats with 43-percent support, compared with 34 percent for Republicans.

In the latest poll, 37 percent of independent voters said they would vote for a Republican, while 26 percent said they would go with a Democrat — a big swing from the October survey that showed Democrats with a 32-30 advantage among independents.

Still, the poll wasn't all good news for the GOP, as 73 percent of voters say they still disapprove of Republicans in Congress, compared with 20 percent who support them. The Democrats' disapproval-approval rating slightly better at 62-30.

Disapproval also runs high for congressional leaders of both parties as well, the poll shows. Fifty-eight percent of voters disapprove of House Speaker John Boehner, R-Ohio, while only 26 percent approve of him. House Minority Leader Nancy Pelosi's disapproval-approval rating was 55-31.

In the Senate, 52 percent of voters disapprove of Majority Leader Harry Reid, D-Nev., while 27 percent support him. Minority Leader Mitch McConnell, R-Ky., had a disapproval-approval rating of 46-27.

"In Washington today, it comes down to who the voters dislike the least," said Tim Malloy, assistant director of the Quinnipiac University Polling Institute. "There are no heroes."
