Sen. Rand Paul (R-Ky.), who is up for reelection in 2016 -- the same year he could be a leading GOP presidential candidate -- is seeking a clarification of Kentucky law that would allow him to run for both offices concurrently.

Kentucky state Senate Majority Leader Damon Thayer (R) told the Washington Times on Monday that he is lending a hand in that effort.

“Yes, I am working on clarifying an ambiguous state law that Rand Paul believes is unconstitutional if it is interpreted to bar running for reelection to the Senate and for president at the same time," Thayer said.

Paul has signaled before that his team has looked into the state law, but Thayer's words signal that action could be forthcoming.

Paul's presidential ambitions would probably only affect his reelection campaign if he won the GOP nomination for president, because most states hold their presidential primaries before their state primaries.

Some states, however, do allow a candidate to run for both president or vice president and reelection on the same ballot, as was the case with Democratic VP nominees Joe Lieberman in 2000 and Joe Biden in 2008.
