Steve Chapman, a member of the Editorial Board of The Chicago Tribune, Why Obama should withdraw (h/t HeyTammyBruce):

When Ronald Reagan ran for re-election in 1984, his slogan was “Morning in America.” For Barack Obama, it’s more like midnight in a coal mine.

The sputtering economy is about to stall out, unemployment is high, his jobs program may not pass, foreclosures are rampant and the poor guy can’t even sneak a cigarette.

His approval rating is at its lowest level ever. His party just lost two House
elections — one in a district it had held for 88 consecutive years. He’s staked
his future on the jobs bill, which most Americans don’t think would work….

But there is good news for the president. I checked the Constitution, and he is
under no compulsion to run for re-election.

It is, in fact, the only way he can win.

But you knew that.
