Hank, in case you hadn't noticed, liberal is no longer a pejorative in the American Political Lexicon...........

I mean, sure it is on Fox, but that's about it these days.
Not only that, many of the Hosue, and a few of the Senate Dem pickups were by 'moderate' Dems in swing states. The House class of 2006 seems to be holding those seats just fine, many crusing to victory this year, and of course a few very close races also. But only a few.
Calling Democratic candidates 'liberals' is actually what lost the GOP many House seats in 2006. Post poll interviews tended to show that in many cases, the voters knew the candidates from previous statewide elections, and KNEW they weren't liberals, just Dems.
They knew they were being lied to by the GOP, and it's respective candidates, and resented it. They voted for in many cases, people who ran on a platform of 'change', back in 2006.
Another aside here, House polling always shows that voters like their Representative, even if giving Congress a negative rating. re election rates are high, until the electorate starts to swing, then they dip, and return to the previous 'stable' levels of re election.
Every single Dem that has run for election for well over 30 years has been tarred as 'the most liberal' whatever. Sen., Gov, doesn't matter, some how they were all 'the most liberal' If Clinton had won the primary, she'd have been 'the most liberal', instead of Obama. Same would have been true of anyone.
It doesn't wash anymore, another thing interviewed voters have started to say more and more over the last few election cycles.
