AZ sort of baffled me. This map skips over 2008, so its not like it was home state effected by McCain or anything.
That surprised me, too. FL is also baffling.
Romney NE suburban strength, but only relative to long term decline in Republican vote in the region. It carried over to Florida retirees even more so, but was somewhat offset by Hispanic growth.
Note that this strongly suggests Republican problems in CO, NH and about half of VA are actually understated by 2008 and 2012 due to Romney and McCain being non-Southern suburbanites. Conversely, Republicans should be pretty enthused about Ohio going the way of Missouri the next time they nominate a populist.
