NEW YORK (AP) — “Saturday Night Live” cast aside the impeachment vote for a cold open with the Democratic primary debate in New Hampshire.

Former cast members Jason Sudeikis and Rachel Dratch returned Saturday to play Joe Biden and Amy Klobuchar in the NBC comedy. But the debate front-runner was Larry David’s portrayal of Bernie Sanders.

He mocked the computer problems that made a mess of the Iowa caucus results.

“I have an idea for an app,” he said. “It’s called ‘no app.’ No app, no computers, no gadgets, no gizmos. You show up at your polling place, take a number like you do at the butcher, they call your number, you go up to the guy and say, ‘Give me a pound of whatever’s about to go bad.’ ”

Later, David’s Sanders said he didn’t know how it happened that he wound up king of an army of Internet trolls called “Bernie bros.”

“Can I stop them in their tracks?” he said. “Of course. Should I? Yes. Will I? Eh.”

Colin Jost played Pete Buttigieg as the “white Obama” and when asked who won in Iowa, said “Donald Trump.”

Sudeikis poked fun at Biden’s age when told he had 60 seconds to give a final statement.

“The doctor said I had six to eight months,” he said.
