The Battle for South Carolina - Rick Santorum will have appeal, but he's voted against right-to-work legislation, and South Carolina is a big right-to-work state.

Peggy Noonan writes in The Wall Street Journal:

Newt's a battering ram who'll wind up in splinters, but he can do plenty of damage along the way.  The candidate people immediately speak of here when talk turns to the GOP primary is a man named Romneybut. "I like Romney but I could change my mind." "I like Romney but I like Santorum too."

[I]f Mitt Romney wins here, he will win the nomination. And it's likely he will win here—that Romneybut will become Romney. But it's a real question how much damage will be done to him along the way.

People don't embrace Mr. Romney, they circle back to him. They consider him, shop around for something better, decide the first product they looked at will last longest and give value, and buy.

The non-Mitt candidates continue, fracturing the conservative vote. Because no one dropped out after New Hampshire, no consolidation of the non-Mitt vote can begin here and get in the way of the buying. Newt Gingrich, tops in state polls a few weeks ago, has damaged himself by the means and manner of his campaign. Rick Santorum will have appeal, but he's voted against right-to-work legislation, and South Carolina is a big right-to-work state. Ron Paul will have appeal too, not only in the coastal cities but among active and retired military personnel, who've been fighting the wars the past 10 years.
