Elon Musk has chosen his preferred candidate in the New York City mayoral election: former Gov. Andrew Cuomo.

The world's richest man urged New York City voters on Monday to vote for Cuomo, who's running an independent bid against the Democratic nominee, state assemblyman Zohran Mamdani.

He also said that a vote for Curtis Sliwa, the GOP candidate in the race, amounted to a vote for Mamdani.

"Bear in mind that a vote for Curtis is really a vote for Mumdumi or whatever his name is," Musk wrote on X. "VOTE CUOMO!"

Musk joins several other big-named billionaires who have opposed Mamdani's candidacy, some of whom have spent millions of dollars on the race.

They include former Mayor Mike Bloomberg, Airbnb cofounder Joe Gebbia, hedge fund manager Bill Ackman, and others.

President Donald Trump has also said that he preferred Cuomo wins the race, telling CBS News in a "60 Minutes" interview that "if it's gonna be between a bad Democrat and a communist, I'm gonna pick the bad Democrat all the time, to be honest with you."
