Sanitorium got killed in his last senate bid in PA... slaughtered. There is more than one reason... such as, most Repubs got slaughtered in that election in states anywhere near purple... but more importantly, the people knew him better by then. He lost by 16 or 18 points I believe.
I think Romney would do way better in PA... based on being more moderate, and a lot of anti-Obama angst with the coal industry, etc. However, Romney not being the most union friendly would hurt him.
Could Romney win Mass? Maybe... very tough sell there... solidly blue state, and while he did win it at the state level, it's different.
Romney wins N Hampshire, Maine... maybe Rhode Island... loses CT, NY...
Midwestern states are fed up with Obama, generally speaking. Iowa would be a toss up... IN and OH, Romney's... Could Romney win MI? Maybe... He's known there, his dad, etc... They've been tipping more conservative than previously. Wisconsin? Maybe, also leaning more conservative recently... Illinios? Hahahahaha, no way. Missouri? Yes, Obama's lost ground there. KS & the other farm states... yes. MN? Doubtful...
Out west?
UT, AZ, AK... duh... Colorader? Hmmm... toss up. NM? Maybe, slim chance. I think Romney can appeal to hispanics pretty well. Cowboy states & ID? Yes. Oregon? I have no clue. WA? Fat chance.
CA & HI, Romney loses... even a reincarnated, fully vigorous Reagan couldn't win that one these days!
Other states, as I see it..
FL, Romney all the way, lots of retirees from the NE make this almost a shoe in.
TX, duh... most of the south? Pretty solidly red. NC? Toss up. VA? Romney.
This is of course if the election were tomorrow. With continuing to rise gas prices and a still struggling economy, it's looking more and more like Obama loses.
