I have just watched the GOP undercard debate that took place in Des Moines on Fox News. Here are my observations.
Mike Huckabee - He argued that it wasn't question of his message not working, but rather that it wasn't getting out. Frankly what's the difference? Don't get me wrong. He kept up his usual good cheer. While Huck ended the debate by saying, "Hello, it's me," (a la Adele) I have a feeling that is his last hurrah.
Rick Santorum - The only candidate who has been at every GOP undercard debate and he isn't happy about it. Of course, even when he was doing well in 2012 he wasn't too happy either. The fact that he was personally thanking his supporters during his closing remarks leads me to believe that he will exiting the race after the votes are counted in Iowa on Monday night.
