"What I've been doing; continue to put pressure on my congressional representative and one of my two senators (since McCain is hopeless)."
How?
Do you vote for McCain or the Democrat, or not vote?
McCain isn't running for four more years. He had no GOP opposition two years ago. I will never vote for a democrat, have never voted for a dem in my life, though, in his case, I may change my mind about that in four more years -- provided people are smart enough to keep him out of the Whitehouse in '08.
