If 0bama wins it will be the first time in a long time a president gets reelected but his party loses House seats, if that happens. He would also be the first president since Wilson to get a second term by a smaller margin than his first election, assuming the race really is close. Would be good if he comes in with less than 50%, even if he manages to win.
If O has a friendly electorate today - he needs at least D+3 or D+4 to stand a chance.
I don’t see it happening.
