The bumps that Hurt and Perriello are finding on the campaign trail reflect nationwide discontent and suspicion among voters. The latest Washington Post-ABC News poll found that 68 percent of voters lack confidence in Democratic lawmakers, and 72 percent lack confidence in Republican lawmakers.

Only 26 percent of registered voters said they were likely to vote for their current House representative. Among those most likely to vote, 56 percent said they would prefer a GOP takeover of the House.

So we’ve got a pair of polls within the MoE that show that 70% of voters don’t trust lawmakers. We’ve got a deeply implausible poll that shows that 74% of registered voters are going to replace the incumbent. (Consider, for a moment, the odds of 322 seats turning over this November.) And we’ve got people expressing a desire about something that they have basically no input into, which is how people will vote in the rest of the nation, rather than what party they’d prefer to represent them.

Translation: Don’t nobody know nothin’. Pollsters, politicians, or voters, apparently.
