Chris Christie.

49 years old, not a leftie and sharp as a tack. So why isn't the excellent Chris Christie putting himself up against the 8 very ordinary Republican candidates willing to have a go at Obama?

As it stands at the moment, the Democrat is going to win by default next time around!

Christie is probably the only leading Republican who could win, so weak is the rest of the field.
