Every election is. They are called politicians.
The only reasons that a conservative could vote for Romney are Paul Ryan and Obama.
If the Republicans flipped the ticket, I'd vote for it in a second. However, Paul Ryan is nothing but window dressing and will have no influence in a Romney Administration.
I not convinced by the "he's better than Obama" argument. Everyone is. There's not enough improvement over Obama in Romney to convince me to vote for him and assure that we won't have a conservative heading the Republican ticket until 2020, assuming Mitt hasn't accomplished his father's dream of destroying all vestiges of the Goldwater and Reagan Revolutions.
On election day, I'm going to vote for all the conservatives I can find on the ticket which means that Mitt Romney will not get my vote (nor will Obama, of course).
