Unwind? Obama never works at all - which might be a good thing right now
I don't think the President (not Obama - any President) shouldn't be able to play golf, or try to unwind a bit. It's a high-pressure job and he needs some release, especially he can't take vacations (as in, take time completely off work).
Specifically on the issue of going golfing, I find some of this outrage at Obama manufactured - just as I found some of the outrage at Bush manufactured. It's a few hours hitting a ball with a club. Whatever.
But it's certainly true that Obama seems to not be very politically savvy with how his game of golf will play against the backdrop of news of the day/week/month. For an otherwise media-savvy politician, this strikes me as weird.
