Don't think Romney can win the Republican nomination.
His lead (whenever it briefly emerges) is dependent on the right wing votes failing to coalesce. But as the others drop out, they will.
Cain cannot win because he is a policy disaster.
Perry cannot win because he called his base uncompassionate and thus proved himself dumber even than anyone imagined.
Paul cannot win because 10% of Republicans think he is fabulous and 90% sees him as a nut.
Bachmann cannot win because she is bitshat crazy.
Huntsmann cannot win because he has emerged from the Republican pupa in the wrong era.
Gingrich cannot win because - well, he's not up for the presidency, he's in it to keep sales of his products going.
If Aunty Marge only realises it - the vacancy is open. Everyone else is going to lose.
Go Aunty Marge.
