The Democratic National Convention is featuring not only many of politic’s biggest names, such as President Obama, first lady Michelle Obama, and former President Bill Clinton, but also Hollywood luminaries. A dozen A-list celebs — including starlets Lena Dunham, Demi Lovato, Chloe Grace Moretz, Katy Perry, Eva Longoria, Alicia Keys and more — will speak or appear in Philadelphia in support of Hillary Clinton and the Democrats.

Usually, the Democrats’ ability to attract high profile celebrity endorsers is a strength: Millennials and others see the Democrats as the cool kids’ party, and just as they mimic Hollywood fashion trends, they are supposed to take their cues for political preferences from larger-than-life celebrities, too.
