Sanford wisely stayed neutral in the South Carolina primary. DeMint (the real senator) supported Romney and Graham (the girly senator) supported McCain. You can look it up.

Sanford only supported McCain after he secured the nomination. I think you are mixing him up with Lindsey Graham's evil twin, Charlie Crist, the governor of Florida, who jumped on the McCain bandwagon when it became clear that Romney might have a chance otherwise.

Sanford publicly aligned himself with McCain in a March 15, 2008, piece in the Wall Street Journal. Likening the presidential race to a football game at halftime, Sanford noted that he "sat out the first half, not endorsing a candidate...But I'm now stepping onto the field and going to work to help John McCain. It's important that conservatives do the same."[26]

From Wiki

Sanford certainly supported McCain in 2000.
