There is plenty of blame to go around when it comes to gridlock in Washington, but a new poll suggests the GOP continues to bear more of it -- at least in the eyes of Americans.

The Quinnipiac University poll shows 64 percent of Americans blame both parties equally for gridlock in Washington. Another 23 percent blame Republicans, while 10 percent blame Democrats.

When asked whether gridlock is more a result of the GOP's obstruction or President Obama's lack of leadership skills, though, 51 percent choose the GOP and 35 percent choose Obama.

Senate leaders have clashed in recent days over potential changes to that chamber's filibuster rules -- a result, Democrats say, of the GOP's extraordinary efforts for block President Obama's nominees.

Polling has regularly shown the Republican Party in worse shape than the Democratic Party, and the Q poll is no exception. The poll shows 71 percent disapprove of Republicans in Congress -- including 49 percent of Republicans -- while 62 percent disapprove of Democrats.

In a generic matchup, a Democratic congressional candidate narrowly leads a Republican candidate, 39 percent to 34 percent.
