The first time that abomination surfaced was over some office at a local DNC. Southern town, I think. The outcry was such that it was taken down.
The right thing for obama to do is to sternly denounce it, and insist it never be flown again. I'd be so embarrassed, I'd want to fall through the floor, if I were preezy. I'd make a teachable moment about respect for a sovereign flag and what it represents.
