Dems also gain significantly fewer seats in the House and Senate. Senate seats that were won by narrow margins like Minnesota, Oregon and Alaska probably remain GOP.
This is what I'm interested in...does Specter still switch and/or does Scott Brown win without Democrats being close to a filibuster-proof majority? Could Republicans have won the majority in 2010? They weren't able to IRL in large part because Democrats just had too much of a cushion (in the Senate) going into 2010. I guess a lot depends on if the financial crisis still happens.
