I'm not really sure McCain would have made all that many decisions different than what Obama has done. and we all saw the restraint he put on Palin during the campaign.
as of now, the man doesn't even have my support for reelection for state senator. I am just not impressed on how he flops around like a dying fish depending on where he thinks he can get the most votes...
I will also add that I do not think a vote for Bob Barr or Ron Paul equates to a vote for Obama. Sure those votes could have been used to help McCain win, but at some point we have got to stand up to the crappy candidates that both the Repubs and Dems are cranking out and say "Dammit, we want something better!"
That's how I see the votes for Barr and Paul going. Each election cycle, more and more vote for someone other than the top two that are being shoved down our throats, and hopefully someday it will be enough to send a clearer message.
