Aside from who he's running against, why would any TRUE conservative want to vote for...
...a pro-abort?
...a socialistic healthcare pioneer?
...somebody's who's appointed 75%+ liberal judges in his track record?
...somebody who supports global warming?
...somebody who's changed his mind three times on embryos?
...somebody who's changed his mind three times regarding employees with a "sexual orientation" as minority status?
...somebody who promised the homosexual Log Cabin group to take up some of their causes in the 1990s?
Almost to a FREEPER, the reason why they say they support Mitt Romney doesn't have to do anything with Mitt Romney.
That...is sad. (And will sequester the turnout come November...no passionate "get out the vote" will be there)
I am not a Romney fan, but you answered your own question about why to vote for him. Because of who he is running against.
