Katy Perry With Hillary Clinton, Makes It Clear She's With Madam President

Katy Perry helped Hillary Clinton in her home stretch by performing at a concert in the all important state of Pennsylvania.

Perry came out on stage to Janet Jackson's, "Nasty" ... which has had a resurgence of late.

Who's looking forward to Wednesday?
