Yeah, and both the Quinnipiac and PPP referenced in the FluffPo article 700UW posted show Republican and independent turnout as being lower than it was in 2009 and 2010.
Something tells me that's not going to be the case. I think you might wind up seeing more than a few Obama supporters sitting this one out. Interestingly enough, there seems to be more and more data coming out of some of the black communities which shows they aren't the voting block they were in 2008 --- the message is getting out that Obama didn't help them much, doesn't necessarily stand for stuff that matters to them (both abortion and gay marriage tend to get under the skin of the church going crowd), and re-electing Democrats in 2010 didn't worked out too well for them, either.
Harder to say where Marquette and Wisconsin will fall. Marquette had Walker and Barrett tied at 49/49 in the recall race two weeks out, and Walker won that race 53/46.
