Katy Perry's "Roar" has been a theme song at every Hillary rally this cycle, so it's no surprise that it's the center of her closing argument ad.

But what an ad it is. Unlike the dark, dystopian picture Trump paints, Hillary's is full of hope and resolve.

The campaign is running this ad now through Election day in the battleground states of Arizona, Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, North Carolina, Ohio, Pennsylvania and Wisconsin.

Really well done!
