I have no idea. Some like me are completely fed up and will go to the polls and vote for other GOP candidates-but not McCain. I think plenty will stay home and not vote at all which will be a disaster for the GOP in congress. Consider this, the country is closely divided apparently. If only a small percentage of conservatives stay home...the GOP will lose.
I could care a less about McCain, but I think it is a shame about congress.
We lost Congress in 2006 and it had nothing to do with McCain.
