Democrat as I am (or would be if I were an American), I have to agree this is more than a bit much. The Conan parody at least was over-the-top enough that we could laugh with it, 'cause, y'know, Conan. I like Obama and think he's doing admirably so far, but he's not Christ or Maitreya or Mashiach or whomever.
As for the question that's been raised as to why we don't see conservatives putting out similar comics, I'd guess that's because a credible alternative to Obama has yet to emerge. Although I don't have surveys to back me up, I'd wager few Republicans really want Palin as the next president because whatever moral authority she once had and whatever confidence she once inspired are spent.
