Ah but there is a huge difference between the parties that they represent.
Remember that the Jack As...ahem...Donkey's BOO'ed God at their National Convention.
Leave the Presidential ballot box empty if you must, but don't avoid voting for good Christian conservative candidates running on the Republican ticket just because the pseudo con's at the RNC put yet another establishment liberal on the presidential ticket.
I'm not leaving it blank. I'm just not voting for Obama or Romney.
