While filling in for Melissa Harris-Perry on MSNBC earlier this week, Jonathan Capehart discussed rapidly evolving views on same-sex marriage in the South. In the segment, Capehart points to PRRI data that demonstrates the dramatic shift in attitudes about same-sex marriage in the South over the past ten years. In 2003, 23 percent of Southerners supported same-sex marriage; in 2013 that number jumped to 48 percent.
