Notice that the commentors who endorse Obama never actually defend his policies. They don't argue that his economic policy or his foreign policy have been successful in any meaningful way, because obviously they can't.
As far as the "let's show some class" stuff, what can I say. I won't lie. I think that this is a catastrophe. Actually, Obama's victory is a symptom of a catastrophe, rather than the catastrophe itself.
The real catastrophe is the emerging majority of takers. They just want stuff, and they'll vote for anyone who promises to take it from people who make it. It's the root of the economic collapse of Greece, Spain, Portugal, Ireland, etc.
It is socialism, and it works, until you run out of other people's (and China's) money.
What happens when socialism in a democracy collapses, which it must, because it is a parasite that kills its host? We don't know yet for sure, but the riots in Greece suggest that civic disintegration begins.
So what happens after civic disintegration from economic collapse? Weimar and the Kerensky government found out. You get more socialism, without the smiley face.
