Although I loves me some General, one cannot argue that Barack Obama isn't a dedicated public servant and a helluva speaker to boot. (The "Don't You Dare Kill Obama" t-shirts are being designed as we speak. And no, I'm not kidding)
I'm in the " '08 is too early for Obama" camp, but there is an interesting essay (via MyDD) arguing otherwise, in particular making the same point I discussed last year -- extended periods of time in the Senate are deadly for a potential presidential candidate. And, of course, as one is always inclined to agree with arguments that somehow validate one's own opinions, I recommend the essay.
Hey, my arrogance and self-awareness are on two different frequencies, and so can co-exist peacefully in my skull.
