David Vitter — NOW
Reelected in 2010, Vitter and his wife, Wendy, have three daughters. (At left, he’s inspecting a pump station near New Orleans in August 2012.) Palfrey, who ran the escort service, was convicted of money laundering and racketeering in April 2008. Two weeks later, she was found hanged. Authorities concluded the death was a suicide. Vitter has grown in stature in the Senate in recent years, gaining bipartisan respect.
