Anglican here, but I will certainly vote for Romney (and at this point, he is 99% certain to be the nominee) over Obama.
He’s not my first choice, but everyone I liked better has dropped out or never got in. That includes Tim Pawlenty, Jon Huntsman, Gary Johnson, Mitch Daniels and Chris Christie.
I’m not a conservative, but a conservative libertarian, and I don’t care for over the top social conservatives like Santorum. I would have had trouble holding my nose enough to vote for him, though I’m an “anybody but Obama” person.
I’m used to it, the last time either major party nominated someone I could be enthusiastic about was Reagan in 1980. The last time before that was Goldwater in 1964, when I was not yet old enough to vote.
