A record low number of registered voters said they would vote to send most members of Congress back to Washington, according to a Gallup poll released Wednesday.

Only 28 percent said that most incumbents deserve reelection, though 49 percent said that their own members of Congress deserves another term. That number is a "near-record low."

The previous low for incumbent support for Gallup was 29 percent, back in 1992. alt

"Voters' anti-incumbent mood is like nothing Gallup has seen in the past four midterm election cycles," Gallup analysts wrote. "While that could have a negative impact on incumbents from both parties, the greater exposure of the Democrats by virtue of their majority status means greater risk for their candidates."

Democrats admit that the fall midterms will be tough, but have maintained confidence they will hold their majorities in Congress. The party has encouraged its members who supported the healthcare bill to tout their votes on the campaign trail even though it receives split support in polling.

Many Republican leaders have predicted they will win back the House and have said Democrats in tight races who voted yes for healthcare will be doomed in the fall.

The poll was taken of 968 registered voters between March 26-28, after Congress voted to pass contentious healthcare legislation.

Before healthcare passed, incumbent support also reached a new low in the CBS News/New York Times poll, with 8 percent saying they would support incumbents.
