I don't buy it one bit. Gas over $4/gallon, unemployment stuck at a high level, a devaluing dollar, an incoherent foreign policy that broadcasts US weakness, the unpopularity of Obamacare, these (and more) all add up to a resounding defeat (unfortunately closer than it should be, but a defeat nonetheless).
We need to work hard to get rid of the bugger that has brought us the Carter effect on steroids......
I hope that you are correct.
