Asked if He May Ultimately Support Gay Marriage, Rand Paul Shrugs

Hambycast: Rand Paul's campus challenge (CNN)

Charleston, South Carolina (CNN) -- Campus politics aren't always a clear winner for Rand Paul, as he discovered here this week during an appearance at the College of Charleston.

The Kentucky Republican and potential 2016 contender opened with a familiar riff about government surveillance that won predictable applause -- especially from the many students who represented Young Americans for Liberty, the libertarian outfit created from the ashes of his father Ron Paul's presidential campaigns.

Then a young woman in the audience asked if Paul, who sponsored an anti-abortion bill in 2013 that defines life as beginning at fertilization, is opposed to Plan B, the emergency contraception commonly known as the morning-after pill.
