I voted for Obama, and I would have even had McCain remained the man he was in the 2000 primaries simply because I have had it with Republican policies. However, if McCain had remained the man he had been in 2000 and Obama lost, I wouldn't be very disappointed. In 2000, I seriously considered voting for McCain, had he won the nomination, because of his independence. But I think these last 8 years just weren't that good for him, or he got desperate to be President since this is his last chance, or his age has befuddled his mind - whatever, it no longer matters.
I do think, because of McCain's about face, that if he loses this will be his legacy and its a real shame because of the man he used to be.
