I was at C-PAC in 2007 and was in the audience when Coulter THEN made an impassioned speech in defense of Romney. So she has not only endorsed him, but has been doing so for years.
Lots of people endorsed Romney in 2007 who now rip him apart (see Limbaugh, Rush). That’s because the alternative was even worse. I’m going off what I’ve read in Ann’s columns, and it appears to me that she is simply saying he’s inevitable, not her preferred candidate. Could be wrong.
