Right now, Obama is so far ahead in the electoral college (290 votes at a worse case scenario, takes 270 to win), it would take a miracle for Romney to win in enough swing states to change that dynamic. You never know, but doesn't look good.
That's why the screaming rightie wingnuts are starting last night and today to come out demanding Paul Ryan as VP pick. Three outlets, including WSJ, had op-eds demanding Paul Ryan over Portman today. Purpose would be to energize the base.
But Obama campaign will destroy Ryan, because his budget is so terrible regarding tax increases for all but the wealthy, profitizing and ending current Medicare, and adding trillions to the debt.
Portman doesn't have any downside, other than he was Bush Budget Director (will be prove Romney to be "Bush 3" in the campaign ads) The convention is gonna be wonderful! Especially as they are allowing all the crazies: Palin, Trump, Cain - to speak, to try and "energize" every vote they can manage.
