We've never done one of these before - a gubernatorial cattle call. There just weren't enough races last cycle. But this time, we've got a ton, and a very unsettled landscape given the huge number of open seats.
In case you haven't done one of these before, rank the gov seats that are up in 2009 & 2010 in order of likelihood of flipping. (So this includes New Jersey and Virginia.) The traditional SSP way is to include seats held by both parties in a single list (separate lists make comparisons harder). Go as far down the list as you like. If you need some food for thought, check out Swing State's gubernatorial race ratings. Have fun!
