2020 Democratic presidential candidate Andrew Yang is reportedly weighing a campaign for mayor of New York City, a close ally told Forbes on Monday.

The unnamed ally, only referred to as a former aide of Yang’s, told Forbes that the business and tech entrepreneur is “definitely” thinking about a bid to replace the historically unpopular and term-limited Mayor Bill de Blasio. However, Yang has not made a decision yet.

Politico first reported the newest round of speculation on Monday when it reported that a poll is asking New Yorkers which of the candidates on a list of 11 that included Yang should succeed de Blasio as mayor.

If he ultimately decides to run, Yang would automatically become one of the most well-known candidates in the already-crowded race. Other big-names who might throw their hats in the ring are CNN President Jeff Zucker and Staten Island Congressman Max Rose (D-N.Y.), Forbes said. The Democratic Party’s mayoral primary is scheduled to take place on June 22, 2021.

He rose to notoriety during his unexpectedly popular dark-horse bid to be the 2020 Democratic nominee for president. In particular, he made a name for himself in promoting the idea of universal basic income (UBI). The general idea of UBI is sending every American adult a check every month, something that has grown in popularity throughout the coronavirus pandemic, especially after a round of stimulus check sent to millions of Americans back in the springtime as part of the CARES Act.

Since dropping out of the Democratic primaries in February, Yang launched a nonprofit called Humanity Forward to continue promoting UBI. He also joined CNN as a political commentator and started his own weekly podcast called “Yang Speaks.”

Recently, Yang and his family moved down to Georgia to campaign for the pair of Democrats running in the state’s two side-by-side runoff elections for the U.S. Senate. These two runoffs will determine which political party will hold a majority, albeit a razor thin one, during the next Congress. The date of these twin runoff elections is set for January 5, 2021.

The Democrats, Jon Ossoff and Reverend Raphael Warnock, are hoping to oust their respective GOP incumbents, Sens. David Perdue and Kelly Loeffler. If the Democrats sweep both seats, they would hold 50 out of the 100 seats in the Senate and have Vice President-elect Kamala Harris as the tiebreaking vote.
