Former Speaker of the House Newt Gingrich is continuing to ride a wave of support despite revelations from his second wife on Thursday that he asked her for an “open marriage.”

I’ve been in South Carolina all week and I have to say that things have changed drastically since Sunday. At the beginning of the week there were six GOP presidential hopefuls. Now that Huntsman and Perry have dropped out we’re down to four. If one of the remaining group does not have a respectable finish in the Palmetto State, there could be one less.

Needless to say, Thursday was the most eventful day in the presidential campaign season to date. Besides the news of Marianne Gingrich “outing” her former husband, Texas Gov. Rick Perry dropped out of the race and endorsed Gingrich, who later the same day laid into CNN’s John King for beginning the networks Thursday evening debate on the marriage issue. Many of my colleagues in the press feel that Gingrich won the debate.

Yet despite all the negative news the Gingrich campaign had to deal with, I sense he is going to win in South Carolina. Romney will come in second which means Santorum will finish third. Personally, I wish Santorum would finish higher.

Now I am off to see if I can find some undecided voters among the tourist in Charleston. At least the whether is nice. More to come.
