Michael Bloomberg Michael BloombergBloomberg rolls out M ad buy to boost Biden in Florida Democratic groups using Bloomberg money to launch M in Spanish language ads in Florida Bloomberg pays fines for 32,000 felons in Florida so they can vote MORE is dropping tens of millions of dollars on a new national television ad, according to a report from The Associated Press.

The buy is in addition to Bloomberg’s already-outsize spending on advertising. When he entered the race for the Democratic presidential nomination late last month, the billionaire businessman and former New York City mayor rolled out a $37 million ad buy spanning roughly 100 media markets.

Bloomberg’s campaign did not offer an exact figure for the cost of his latest national ad spot, but said it was similar to his initial buy, the AP reported.

The new national ad buy is set to begin airing on Wednesday in all 50 states and will continue over the next two weeks, according to the AP report.

Bloomberg’s campaign did not immediately respond to an inquiry from The Hill.

“Mike Bloomberg’s never been afraid of tough fights – the ones that make a true difference in people’s lives,” the ad says, according to the AP. “And Mike’s won them.”

But before he can take on Trump directly, Bloomberg will have to get through a grueling primary race in which he faces rival Democrats who have been campaigning much longer than he has.

At the same time, Bloomberg has already begun facing accusations that he is seeking to buy the Democratic nomination by throwing millions from his personal fortune into his campaign.

He has other political liabilities, as well. He only registered as a Democrat in 2018 after spending more than a decade as an independent. Between 2001 and 2007 he was a registered Republican.

He has also faced questions about his record as New York City’s mayor, particularly his advocacy for so-called stop-and-frisk policing strategies that disproportionately targeted men of color. Bloomberg apologized last month for pushing those policies, saying that he was wrong to do so.
