Former New York City Mayor Michael Bloomberg might be willing to spend at least $100 million on a 2020 presidential run, CNBC reported Thursday, and likely even more.

“Mike spent more than $100 million in his last mayor’s race. Last time I looked, NYC is a fraction of the size of the country as a whole,” Howard Wolfson, a political adviser to Bloomberg, told the news outlet in an email.

That would be a sizable chunk of one’s personal wealth to devote to an election. By comparison, President Donald Trump spent $66 million of his own money on his 2016 run.

Bloomberg, who is No. 11 on the 2018 Forbes’ Billionaires List, chipped in $110 million to help Democrats in the 2018 midterm elections. When CNBC asked if he’d be willing to spend a similar amount on his own campaign, Wolfson seemed to suggest money would not be a problem. “Whatever is required,” he said.
