What's Mallard raving about today?
Barack Obama's Supporters.
Much like the Rich Grumpy Old Man, Mallard's line of attack here is not so much an attack on Obama, but essentially an attack on his supporters as mindless celebrity-worshiping idiots.
Thus removing all doubt, if there ever was any, whether Senator I-don't know-how-many-houses-I-own will continue the divisive President of One-Half of America politics of President Bush. Less an attack, it is an admission that McCain is McSame.
The racism thing? All I can tell you is that Mallard must hear that charge a lot, and it's always the other person's problem. Nothing to do with him.
