Gotcha.
I find it funny when people say, "They're both bad." That's just not true. Obama's campaign has avoided mud slinging (I don't consider ads that criticize the issues to be mud slinging, only ones that stray from them) and has run many ads that are positive (i.e.: Obama sitting in a chair, talking about his plans). Obama has responded with a cool, calm, and collected manner. He's responded to every criticism (that he lacks substance, that he's associating with terrorists, etc.) with solid reasoning.
McCain has done almost the opposite. Obama has run the first clean campaign I've seen in America. He's not resorted to fiery tempers, desperate measures, or blatant lies, as his opponent has. And, in the most important decision of the campaign (the VP selection), he made a solid, smart choice, whereas McCain made a desperate, short-sighted, flat out stupid political choice.
Obama >>>>>>>>>>>>>>>> McCain
