For me, the main thing about the Obama presidency is that it re-sets my default mood. Since Bush v. Gore and the judicial coup d'etat of 2000, my default political mood has been pissed off. Occasionally things would make me more pissed off or less pissed off, and once in a blue moon I'd be happy, but pissed off was the baseline from which everything started. And that was before 9/11 and Iraq.

Now, with a President who can speak in complete sentences, who believes in the rule of law, who believes in hiring people for their competence and ability rather than their personal loyalty and religion—my default political mood is happy. Things will piss me off about Obama, I'm sure, and some things will elate me: but the baseline is changed from pissed off to happy, and that's a huge shift.
