The ranks of those who have any doubt about the outcome of the Republican presidential race got a bit thinner yesterday when Senator Marco Rubio endorsed Mitt Romney. The Tea Party favorite’s backing of Romney is yet another sign that even hard-core conservative Republicans have come to the conclusion the only way to win in November is to close ranks behind the frontrunner. With Rick Santorum looking at almost certain defeat in the next round of primaries to be held next week and Newt Gingrich having basically thrown in the towel, the prospect of Romney as the GOP nominee has now gone from being likely to almost certain.
Rubio’s endorsement, along with recent comments from other Senate conservative stalwarts like Jim DeMint and Pat Toomey vouching for Romney’s bona fides, should help ease the way for the rest of their party’s right-wing to start coming back in from the ledge onto which they had walked during the winter. As many on the right have spent much of the last year speaking of Romney in the most harsh terms, it’s not going to be easy for them to walk back the charge that he is indistinguishable from President Obama and a certain loser in November. But as is always the case in politics, once the bandwagon starts rolling, it gets easier to hop on. But even as he formally put himself behind Romney, Rubio also continued to discourage talk of the vice presidency.
