stopping Mccain in South Carolina primary

[rob in cal]

I wonder if Mccain could have been defeated by Huckabee in South Carolina, a result which may have deflated or slowed down Mccain's momentum going into the Florida primary.  The results were close, about 33-30% with Thompson and Romney getting another 30% combined.  I wonder if the 30% who voted for Thompson and Romney potentially could have been galvanized into a stop Mccain movement, as you would think that most of the voters for those two candidates would lean more conservative and might have rallied to Huckabee in South Carolina not because he was a great candidate, but merely for the strategic purpose of tripping Mccain up, thereby stopping the front-runner.
    I remember on the Friday before the vote that Saturday that talk show host Hugh Hewitt, who was extremely pro-Romney, urged everyone to vote for Huckabee in South Carolina, just as a way to stop Mccain from getting another cheap nowhere near a majority victory.
