Mark Sanford picked up an endorsement Tuesday from U.S. Sen. Rand Paul.

Paul, a tea party favorite and potential 2016 presidential candidate, touted the former GOP governor’s fiscal conservatism.

“More than anything, Washington needs strong and consistent voices for fiscal responsibility and liberty,” Paul, R-Ky., said. “Mark has proven during his time in office that watching out for taxpayers and holding the line on spending are his top priorities. What we absolutely cannot afford is someone like his opponent, who will be yet another vote for a return to the Pelosi speakership, for disastrous programs like Obamacare, and for more spending and debt. I am pleased to endorse Mark and stand with him in this race.”

Paul’s father, former U.S. Rep. Ron Paul, also has endorsed Sanford in the 1st Congressional District race. Sanford faces Democrat Elizabeth Colbert Busch and Green Party candidate Eugene Platt in the May 7 election.
