The three remaining big candidates in the GOP race (sorry, Ron Paul) have talked about how they would handle it if another candidate were to jump into the fray.

The Weekly Standard's Stephen Hayes says the three met in Ohio and discussed throwing their support behind the eventual nominee, no matter who won, for the good of the party.

The three candidates discussed the nominating process. Romney raised the possibility of an unvetted candidate getting into the race and spoke of the perils such a scenario presented for the party. Not surprisingly, the other two assented and each agreed that he would reserve his support for someone now in the race. R.C. Hammond, a spokesman for Gingrich, said the consensus that emerged from the conversation was that the Republican nominee was among “the four of us” and not an outsider. Eric Fehrnstrom, a senior Romney adviser, agreed with that characterization.

Despite the consensus that emerged from the discussion in Wilmington, Gingrich twice raised the possibility of a new entrant in an interview last week with Bret Baier on Fox News. Gingrich pointed to Romney’s difficulty winning support from conservatives. “I’m just saying analytically​—​the way we campaigned out here, the fact that two out of the three delegates from each state is not going to be for Romney​—​is a significant advantage. We can argue later on whether Santorum is the right person to nominate or Gingrich is​—​or something else may happen.”
