Kentucky Republican Sen. Rand Paul tapped his brakes this weekend on a potential 2016 presidential run, saying his wife has yet to support the idea.

“Where’s my cellphone? Can I call my wife?” Paul said jokingly after a speech Friday night in Detroit. “There are two votes in my family. My wife has both of them, and both of them are ‘no’ votes right now.”

Whether the popular, first-term senator was totally joking or just playing coy remains unclear, with early polls showing him, New Jersey Gov. Chris Christie and Florida Sen. Marco Rubio consistently among the Republican Party’s top potential 2016 White House candidates.
