A South Carolina Republican congressional candidate wrote House Speaker Nancy Pelosi (D-Calif.) on Monday to invite her to his district.

State Sen. Mick Mulvaney, a Republican challenging Rep. John Spratt (D-S.C.) this fall, wrote the speaker to invite her to South Carolina's 5th Congressional District to talk healthcare reform.

Mulvaney's campaign released a letter noting Pelosi's willingness to campaign for Democrats, and said it was an opportunity to come to South Carolina.

"Therefore, I invite you to come to the 5th District of South Carolina," he said, in a letter provided to the Charleston Post and Courier. "As you know, it is the home of your Budget Committee Chairman John Spratt."

The letter is no doubt a stunt on behalf of Mulvaney, since Pelosi is unlikely to travel to the district — at least at the Republican's request. It reflects, though, a sense among Republican candidates that the Speaker is a liability for endangered incumbent Democrats, some of whom have been debating whether or not to appear with Pelosi or even more senior party leaders like President Obama.

Mulvaney's letter needles Spratt, the chairman of the House Budget Committee, by looking to link him to Pelosi on a number of policy items, especially ones unpopular in their relatively more conservative district.

"Many of us in South Carolina remember his impassioned introduction of you on the night of the final vote of that historically bad bill," he said. "Certainly, by any measure, he has earned your support in this election."
