Sen. Rand Paul (R-Ky.) suggested Friday that he wants to run for president in 2016, but he said that he's first got to convince a very skeptical wife.

Paul was asked about running for president after a speech at the Detroit Economic Club, which led him to ask, "Can I call my wife?"

"There's two votes in my family," he said. "My wife has both of them. Both of them are 'no' votes right now."
