Mayor Bill de Blasio reported raising more than $428,473 for his re-election bid during the most recent campaign finance filing period, expanding his cash-on-hand war chest to $2.5 million and his total fundraising count to $4.9 million.

His fundraising so far qualifies him for nearly $536,000 in city matching funds — money he said he’d gladly accept, even though his opponents will likely have access to only a fraction of the taxpayer-funded financing.

“I believe in the program. I’m going to follow its rules,” he said Monday.

Meanwhile, Assemblywoman Nicole Malliotakis, the presumptive Republican nominee, raised nearly $250,000 for the most recent filing period and spent $74,097 during that time.

She’s eligible for $134,804 in matching funds and has raised a total of more than $344,000.
