He’s clearly addicted to funny money: Now Mayor Bill de Blasio’s been caught violating federal campaign law by using his state Fairness PAC to jumpstart his White House run.

Not long after shutting down the scandal-plagued Campaign for One New York, the mayor set up the NY Fairness PAC — supposedly to boost likeminded candidates across the Empire State.

But recent filings show that the state committee spent $68,000 on prez-race polling that it didn’t report to the Federal Election Commission, plus another 52 grand on other 2020 expenses, including $40,000 for the consultants who did his campaign-launch video, more than $8,500 for “launch weekend travel” and $4,200 to rent his prez-campaign office in Brooklyn.

De Blasio’s federal campaign now lists a debt of $52,852 to the state PAC. Problem is, as The Post’s Nolan Hicks reported, “Federal law bars state groups — like de Blasio’s — from contributing more than $2,800 in cash, loans or purchases to a federal campaign during the primary election.”

As Tyler Cole, a top lawyer at DC-based watchdog Issue One, told The Post, “You can’t allow candidates to use state committees to do an end-run around the law.”

In 2017, Hizzoner infamously dodged federal and state prosecution for fundraising abuses, and a long-suppressed Department of Investigation report found that his use of CONY violated city ethics rules.

He plainly figures he’ll get away with it again, even telling Politico that his “I’m running for president” campaign-launch video wasn’t a campaign expense.

The FEC should fine him big-time — not just for blatantly violating the laws, but also for being so smug about it.
