This is a very good test for both Sarah Palin, and for Mitt Romney.
Last time around, Palin stood down at the last minute, more or less handing the GOP nomination to Mitt Romney.
Good or bad, she did. Mitt won the GOP nomination.
However he lost the election.
This time there will be a completely open field, both parties are starting over.
Sure there are some favorites, but a lot will happen before the actual elections start.
I think Palin and Romney could be very big.
Maybe not, but I think so. Real knock-down sort of competition between the two camps.
