Were it not for Piscataquis County, Maine, Obama would have won every county in New England. I'm pretty shocked Essex County, Vermont swung as hard as it did.
New England is really evolving into a kind of modern version of the Solid South. It's hard to see how Republicans can retain their current Governorships and Senate seats in the region in the long term with no House seats at all in New England and sitting in a distant minority in all of the state legislatures (except maybe the Maine Senate; anyone have results for the election there?)
Edit: Well, the new Maine Senate looks to be 20-15 Democratic. Not awful for the Republicans, although it's a slide backwards from the previous 18-17 split.
Not the current Republican party at least.
PA should be included in the Northeast's slapdown of the GOP...it was the Philly area that provided Obama's huge majority, even as McCain improved in the midwest-esque part of the state.
