Sixteen years ago, it was her husband's turnaround to finish second in New Hampshire that earned him the nickname "The Comeback Kid". Last night, Hillary Clinton won in the granite state against all the odds (apparently, UK bookies were offering 8/1 against her) as well as the polls which showed a ten-point lead for Barack Obama. In the Republican primary, John McCain also turned things around to take first place. So, four elections (two each for the two parties) and four winners. What have we learnt, if anything, so far?

I'm not sure we've learnt anything other than that polls are unreliable and that this election really could see anyone representing either party. It's going to be exciting over the next 300 days to see how it pans out.
