“That’s exactly what you are doing if you give the election to the democrats.”
But, they’ll prove a point...
The point will be that Conservatives are not reliable voters and that therefore conservative issues lose, and supporters of conservative issues lose.
If you don’t want to vote for McCain, then write in/protest vote for POTUS. A split ticket speaks volumes. Staying home just says that Conservatism isn’t worth supporting because you cannot get elected because conservatives stay home unless the nominee is PERFECTLY conservative. So why run as a conservative for a lesser office if that guarantees a loss?
