Michael Bloomberg says he hasn’t decided whether to run for president yet, but he sure is looking more and more like a candidate. CNBC reports:

Billionaire Mike Bloomberg is prepared to spend well over the $100 million he put into his last campaign for New York City mayor if he runs for president in 2020. And he does not plan to accept any outside money from political action committees if he jumps into the race.

A USA Today poll out this week asked people how they would feel about certain candidates running in 2020, Bloomberg included. The newspaper reports:

Michael Bloomberg was an “exciting” possibility for 20 percent, but 32 percent urged the 76-year-old not to try, a net negative of 12 points. He re-registered as a Democrat in October for the first time since leaving the party in 2001.

Meanwhile, in an interview with Meet The Press’ Chuck Todd (watch above) Bloomberg made clear that climate would be a major issue for him. He said:

“Any candidate for federal office better darn well have a plan to deal with a problem that Trump science advisors say could end this world. Even his science advisors.”
