"Why do you a professed conservative want to support a liberal?"
Being conservative on foreign, ecomonic, and domestic policy and being liberal on social policy doesn't make you a liberal. It averages out to be moderately conservative. Also, its stupid to vote for the president on social issues since these are mostly state issues and the president has very little influence on this issues. You have to vote for the most electable candidate that you agree the most with on the issues that are the most important and the president has the power to affect in a significant way.
"Particularly when there are conservatives to support"
All of which will lose if nominated!

One hole in argument is that Rino Rudy is so far to the left he is also unelectable as a republican. Make a great rat though.
