This whole conversation is incredibly moot since Rick Snyder will not win reelection in 2014.
Yes, he will.
Uh did you see today's PPP poll? It looks REALLY good for Schauer. His name recognition is atrocious yet he ties Snyder, and Snyder's approval rating is absolute garbage. And Snyder's "right to work" law is unpopular. It's Michigan, so undecideds will break Democrat, and like pbrower said, GOTV from big labor as well as a general increase in Schauer's name recognition (and as a result, popularity) will get Schauer over the line.
To be fair, no other pollster shows Schauer doing so well (coincidentally, or perhaps not, PPP is the only recent pollster there to not use an LV screen). Of course, many of these other pollsters were dead wrong in 2012. It would be nice to get a good pollster in Michigan to see if the results are similar to PPP, but that's probably too much to ask.
