“The Big Short” director Adam McKay went on a tear against the Democratic Party in the wake of President-elect Donald Trump’s victory Tuesday, declaring he’s ditching the party for good.”It is time to abandon the Dem Party,” McKay wrote on X. “I’m registering Green Party or Working Families. But am open to ideas.”The director ripped the Democratic Party for what he deemed a series of missteps leading up to Election Day, including how they handled President Biden bowing out of the race to make way for Vice President Kamala Harris on the ticket. “Who would have guessed lying about Biden’s cognitive health for 2 yrs, refusing to do an open convention for a new nominee, never mentioning public healthcare & embracing fracking, the Cheneys & a yr long slaughter of children in Gaza wouldn’t be a winning strategy?” he said.PRESIDENT-ELECT DONALD TRUMP’S VICTORY SENDS HOLLYWOOD INTO TAILSPIN”Anyone with half a brain?” he continued. “But I thought liberals’ whole thing is being smart? It’s not? They actually just blindly cheer the parade of rickety optics wrapped up in New York Times fonts that is the modern Dem Party?”McKay has in recent years championed progressive causes and has donated millions of dollars to fight climate change. His activism has also bled into his work. His movie “Don’t Look Up,” for instance, served as a critique of a lack of action when it comes to protecting the environment. The 2021 satire film centered on two scientists who try in vain to warn the world about a planet-destroying comet.Climate change is “extremely alarming, extremely frightening, and quickly becoming the only thing I’m thinking about on a daily basis, even as I’m writing scripts and directing or producing,” McKay said in an interview with The Associated Press.KEVIN O’LEARY CLASHES WITH CNN PANEL, SAYS DEMOCRATS ‘CIRCUMVENTED DEMOCRACY’ BY SELECTING HARRIS‘DON’T LOOK UP’ DIRECTOR DONATES $4 MILLION TO FIGHT CLIMATE CHANGEOther celebrities opened brutal autopsies on the election or expressed outrage at their fellow Americans.Actress Christina Applegate repeatedly asked “why?” on X.”Why?
