Democratic candidates said that they hear regularly from voters about abuse of the parliamentary tactic, which is likely to come up as the first vote new senators face in 2011. The supermajority requirement in the Senate has become such an obstacle to reform that it infiltrates policy discussions at every step. Last week at the Netroots Nation political conference, Sen. Ben Cardin (D-Md.) gathered environmental writers to discuss energy legislation; the first few questions were related to energy, the rest of the conversation was dominated by the filibuster.

"The use of the filibuster and the way it's led to backroom deals has created the impression in the heartland that the Senate is dysfunctional," said Jack Conway, a Democratic candidate facing Republican Rand Paul in Kentucky. "They don't understand why Washington can't address the issues people care about. People in Kentucky wanted people focused on jobs -- 14 months [of the health care debate] laid bare how broken the system was."

Conway was joined in his backing of filibuster reform by the three other Senate candidates who HuffPost interviewed for this story: Paul Hodes of New Hampshire, Elaine Marshall of North Carolina and Roxanne Conlin of Iowa. Sitting Senators Al Franken (D-Minn.), Ben Cardin (D-Md.) and Jeff Merkley (D-Ore.) also said they supported reform.

"It's not constitutional. It's not statutory. It's a rule," said Hodes, adding that he wasn't certain what the new rule should look like exactly, but the current ones needed to be reformed. "Everywhere I go, they say, 'Make 'em bring out the cots and the telephone books.' People are eager for real backbone and some toughness from Democrats."
