It's hard to say how the GOP would do in CT with a well-behaved nominee. They haven't had one in so long.
Exactly, which is why Romney's numbers in the state should be taken seriously. 2012 could be the opportunity for Republicans to significantly gain a presence on the electoral map again. The last comfortable win for them was all the way back in 1988. Remember Democrats went through a period from roughly 1972 to 1992 where they were either in the wilderness in presidential elections, or couldn't manage to break 300. Yet, Clinton came along and significantly altered the map for them, and arguably gave them an electoral vote advantage they have maintained, and will likely lose come 2012.
Clinton may have helped Democrats in the electoral college, but he destroyed them at the Congressional and local level, which Obama made even worse. As a Democrat, I would rather have control at the Congressional and local level rather than at the Presidential level. As you can see from Obama, having the White House means basically nothing.
