I believe he can still win, although it would be a long shot. Viriginia has a winner take all primary 63 delegates, while a big win in TX and OH could really boost his count. Throw in that he will do well in the other smaller states and I think he can make up substantial ground and go to the convention with neither he or McCain as the outright nominee.
If he wanted VP, he would just get out now that Mitt is out and claim his prize.
Can Mitt still win? Frankly, no – the arithmetic makes it all but impossible The Republicans have already chosen most of their delegates, and Romney has won only 256 of the 1,417 chosen so far—some 18%. To get the delegates he needs to lock up the nomination, Romney would not only have to improve his performance, he’d have to become virtually perfect – winning 934 of the 963 delegates who haven’t yet been chosen. Unless all other candidates dropped out of the race, there’s no way anyone will scoop up more than 97% of the delegates remaining. Even if Mitt gives the greatest speech of his life at tomorrow’s conference of CPAC (the Conservative Political Action Committee) he can’t win enough delegates to become this year’s nominee. Huckabee can only win if hell freezes over. But that’s not going to happen; instead, it’s his campaign that’s frozen over.
Its impossible for Huck to get enough delegates to win the nomination. Do the math.
You can forget TX. John McCain will win overwhelmingly since Mitt is out. Trust me, it is fact.
