Mitt could not buy a primary victory once it won’t happen the second time he tries.
I agree that he is a formitable candidate, up to a point.
Mitt Romney financed a huge part of his own campaign in 2008. He was in it early, spent tons of money, and... ended up right about where he started, as far as a percentage of people who supported him. Romney started and ended with about 20% of the vote, not enough to win anything.
Apparently, there was no amount of money to make him popular enough to win, not to say he didn't try.
What makes Romney formidable, then, is his ability to choke out other candidates who may have less money, but have excellent ideas. Another Mitt Romney candidacy will leave conservatives with the same thing they had in 2008: a candidate like John McCain who can't win, but can raise money due to his connections and time in Washington.
Worse yet, the specter of a successful Romney campaign, which will by necessity drag the GOP lurching toward the center and away from conservatism for the foreseeable future.
