Filmmaker Michael Moore is back and this time, he has a supporting cast of rising progressive candidates.

One of those is Alexandria Ocasio-Cortez , the New York congressional candidate who unseated a powerful Democratic incumbent in the primary this June.

The definition of electoral insanity is trying to re-elect these same guys over and over again, and expecting our country to be any different, Ocasio-Cortez explains in an exclusive clip from Moores upcoming documentary Fahrenheit 11/9.

She is one of several progressive rising stars featured in the film, which the Bowling for Columbine and Fahrenheit 9/11 director hopes will help bring down President Donald Trump .

Trumps election, as well as dissatisfaction with the Democratic Party s leadership, has catalyzed a wave of progressive candidates in this years midterm elections.

The revolution is happening in the most unlikely of places. The resistance the true resistance is not coming from the Democratic Party or from the liberal establishment, Moore told HuffPost last month .

Also featured in the clip is Democratic congressional candidate Rashida Tlaib , from Moores native Michigan, who will become one of the first Muslim women in Congress if she wins as expected in November.

Were not ready to give up on the party, Tlaib tells Moore in the film. Were just ready to take it over, and lets put some people in there that get it.

Watch the clip above. Fahrenheit 11/9 premieres in theaters on Sept. 21.
