Well, I’m just not going to vote for an abortionist/homosexualist/statist. I stated that fact when Romney and Rudy first declared their intentions to run for the presidency many years ago and I have no intention of ever changing.
It seems it would be far easier for Romney to repudiate his support for statism / genocide / perversion, than to convert all of those who simply can’t get behind him otherwise. Maybe he’s trying to throw the election to Obama.
