I don't know if anyone has ever trailed for literally the entire campaign in every single poll for many many months and come back to win in the final month or two, which is what Santorum would have to do.
Charlie Cook said that Santorum's been "behind since Moby Dick was a guppy."
My gut tells me that Santorum has a better chance, but I think a lot of people are going to be very surprised about Tennessee come Election Day. Ford has run an unbelievably good campaign, probably the best of the year.
