Well, if anybody knows how to shake his money-maker, it’s a billionaire.

Democratic presidential candidate Tom Steyer got down and dirty with Juvenile on the campaign stage Friday night in Columbia, South Carolina, thrusting his hips and wiggling his butt to the rapper’s 1999 hit “Back That Azz Up.”

The awkward display came at a primary-eve rally at Allen University, a historically black college, where Steyer wooed a half-empty gym with pounding music and a dazzling light show, BuzzFeed reported.

Democrats head to the polls Saturday for the first nominating contest in the South, where Steyer, a billionaire investor, has swamped the airwaves with millions of dollars’ worth of ads — but is in a distant third place behind Joe Biden and Sen. Bernie Sanders, according to the RealClear Politics polling average.
