The boss looks to tomorrow's contests and concludes:

If McCain wins South Carolina: Thompson's probably out. Huckabee presumably stays in and continues to get delegates, but it's hard to see how he can be the nominee (if he can't win South Carolina, how many other states can he carry?). McCain would have to be favored to win Florida, as former Thompson voters gravitate to him, and some deserting Rudy supporters as well ... and with a victory in Florida, McCain would become the frontrunner going into Feb. 5. If McCain loses (but Thompson doesn't win): Florida becomes an even, four-way race, whatever happens there all four probably then stay in for Feb. 5, the primaries that day split in multiple ways. ... Who knows? If Thompson wins: A five-way race.
