"Lastly, if you indeed want McCain to lose I'd like to see where you have made some level of commitment to the Obama campaign"
Why do you presume that if someone doesn't want McCain, they have to commit to working for and/or supporting Obama?
It is perfectly legitimate to criticize BOTH candidates, and want neither. Millions of Americans feel and act this way in this election, and in every election going back most of their lifetimes!
I couldn't have supported either candidate (had I been old enough to vote in it) in the Ford vs Carter election either.
