Quote from piezoe:
Portman would be one of the more sensible choices and would benefit the ticket. I still view Romney as another throw away candidate just as McCain was. This election will be the last we hear of Romney as a candidate for president, but Portman may use this opportunity, if Romney gives it to him, to become more widely known in national politics. The strongest Republican candidates will surface in time for the 2016 lunatic show. The economy will still be in the dumps, and residential real estate will have just made or be making a bottom, unemployment will still be too high. The Republicans will fight tooth and nail for the nomination, as the anointed one will almost certainly gain the White House. It could be Portman as long as the crazy wing of the party doesn't sabotage him for not being nutty enough and he hasn't yet misspelled "potato" on national TV, molested any underage boys, propositioned his secretary, or abandoned a dying wife. If he gets the nomination, he will get good support from independents.
Christy may throw his hat in the ring for the 2016 election, but he won't get the nomination and that will be the end of his presidential aspirations. If he works hard enough for the eventual candidate and delivers New Jersey's electors into Republican hands, he could get a cabinet appointment, but that's as far as his mouth -- in two ways--will permit him to go.
Portman was a major player in the Bush administration.Romneys security team already has over 23 Bush security advisers, with Portman as VP Obama could run against Bush again
