A year from now, who will already be tipping a 2016 run?

I think Biden will wait and see if someone good gets in before making a final decision on whether or not to run. If the field looks too weak by 2014, he'll toss his hat in the ring, if not, he'll retire. In any case, I look for a real battle on the Democratic side to inherit Obama's massive campaign machine. While Obama may prefer not to endorse until the Democrats have a nominee, it won't prevent candidates from trying to woo his contributors.

Right now, the Republican field looks pretty weak, so weak that Santorum might end up running as a sacrificial lamb in 2016 unless someone emerges from left field that's truly impressive.
