"It's not surprising dem registration is down relative to R registration in 2008. In 2008 there was a hotly contested primary in the democratic party, and you had to register as a dem to vote in it in many states. In 2012 all the primary action was in the republican party, while the democrats went uncontested." - AaronTX
