The energy of the 2010 midterms hasn’t gone away.
I do think conservative turnout will be high like in 2010, but democratic turnout will be higher than 2010 so I don’t think you can reset the polls to those numbers. Blacks, for instance, never turnout for midterms. I do think dems are oversampled a bit, but not to the extent the unskewed polls showing Romney with a significant lead by using 2010 numbers. My opinion is that I agree with Rassmussen and it is somewhere in the middle and it is essentially a tie right now.
