Liberal documentary filmmaker Michael Moore says that he would “join a million other people surrounding the United States Capitol” to prevent President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

“I will stand there. Bill, let me tell you something. If this judge goes through, for at least the rest of our lives, it’s a right-wing court. That’s it. It’s over,” Moore said while speaking on Bill Maher’s HBO show "Real Time."

On the show, Moore urged liberals to have hope that Democrats would be able to block Justice Anthony Kennedy’s successor to the Supreme Court, despite Democrats not being able to filibuster the nominee.

“The Senate right now is 50-49. Sadly, [Sen. John] McCain [R-Ariz.] will not be able to vote, so it’s a 50-49 vote,” Moore said, arguing that Democrats should be able to push off a vote until November.

“And I don’t trust every Democrat,” he qualified.

Conservative columnist Jennifer Rubin proposed her own tactic on the show of calling for people to boycott key businesses in states with senators whose votes could be on the fence.

“Instead of circling the Capitol with a million people, take the million people to Maine and go to L.L.

“That’s how you play hardball. You do it smart. You go to Alaska, you say, ‘You know what, we’re gonna start boycotting Alaskan cruises until your senator votes Trump’s way,” she added.

Some Democrats believe the pair could vote against Trump’s forthcoming nominee to the court, while Republicans believe some Democrats running for reelection this year in red states could defect and vote for the nominee.

The battle to replace Kennedy kicked off in earnest this week after he announced that he would step down after 30 years on the court.

While Kennedy was nominated by former President Reagan, he was sometimes seen as a relatively moderate voice on the court who often cast the deciding vote in a number of high-profile cases.

During his tenure, he sided with liberals to advance LGBT rights, save ObamaCare and limit the death penalty while voting with the conservative wing to protect religious liberty and limit campaign finance laws.

Democrats fear that his replacement could undo key rulings like Roe v. Wade, the landmark 1973 case establishing a right to abortion.
