Republican presidential candidate Jeb Bush is the first person to file for Kentucky's presidential caucus.
Bush filed his paperwork on Thursday during a visit to Louisville for a state Republican party fundraiser. He also paid a $15,000 filing fee.
Kentucky normally has a presidential primary in May. But this year, the Republican Party of Kentucky voted to have a presidential caucus on March 5. That way, Kentucky U.S. Sen. Rand Paul could run for president and re-election to his U.S. Senate seat at the same time without breaking a state law that bans candidates from appearing on the ballot twice in the same election.
Despite Paul's advantage, other candidates have shown interest in the caucus. Thursday, Republican candidate Marco Rubio told Kentucky Sports Radio he planned to compete in Kentucky.
