Pop princess Katy Perry may be taking a break from the promo trail for herself (recently wrapping up her ‘Prism’ world tour on October 18th in Costa Rica), but that didn’t stop her from hopping aboard the promo train of presidential hopeful Hillary Clinton at a recent stop in Des Moines, Iowa.

Did her performance win the crowd’s vote?  Watch below and tell us:
