The popular Governor of Florida has just endorsed John McCain. Charlie Crist's endorsement was most sought by Rudy Giuliani who was once the overwhelming favourite to win Florida but is now trailing in third place. Crist's backing is likely to be enough to see McCain prevail in the sunshine state. Pre-endorsement polling had McCain edging Mitt Romney by just 0.3%. That should lengthen now.
As expected Barack Obama has won the South Carolina primary but with a big racial divide potentially emerging in the Democrat party. Senator Obama has been keen to avoid being seen as a racially partisan candidate but he won 80% of South Carolina's black voters but only a quarter of the state's white voters.
