McCain doesn't even come close to the potential that Obama has as President. I think this could be historic, not just because of race but because Obama could finally bring some sensible policies to the White House. I base this on his ability to communicate. While so many deride his skill, I find it to actually be the most compelling thing about him. On issues where the right choice is a tough choice, I think he can move the needle and motivate people to do the right thing. That's the power of speeches.
So, on top of all of his policy positions and obvious qualifications to be President, this is why I really want this guy to win.
