He’s the financial life of the party.

Mike Bloomberg pumped a combined $800,000 to the Democratic National Committee and 44 state Democratic Party committees while he officially launched his bid for the presidency, new campaign records reviewed by The Post reveal.

The billionaire former New York City mayor wrote a fat $800,000 check to the Democratic Grassroots Victory Fund — a joint fundraising committee for the DNC, the state political parties and the D.C. Democratic Party – on Nov. 19.

Bloomberg officially announced his campaign for president on November 24.

The $800,000 was then redistributed to the DNC and 44 states between Nov. 19 and Nov. 27, campaign records show.

The portion distributed to the DNC was $319,5000, according to records filed with the Federal Elections Commission.

The Bloomberg breakdown in contributions to the 44 state Democratic Parties – all listed under his name in records – totaled $401,000.

Because of legal contribution limits, Bloomberg’s donations directed to the state parties mostly ranged from $7,500 and $10,000.

Even the Iowa Democratic Party collected a $10,000 check even though Bloomberg is skipping next Monday’s Democratic caucus.

The New Hampshire Democratic Party also received $4,999 even though he’s not competing in the Granite State’s Feb. 8 primary.

Bloomberg’s campaign declined comment on the donations.

An FEC spokesman confirmed that Bloomberg’s contributions to the states originated from the $800,000 he donated to the Democratic Grassroots Victory Fund.

“Contributions made through a joint fundraising committee and then transferred to other committees appear twice in our records,” said FEC spokesman Christian Hillard.

It’s another example of Bloomberg — who through the years has been a registered Democrat, Republican, independent and Democrat again — using his massive wealth to support his latest cause – the presidency.

During his tenure as mayor when he ran with Republican Party backing, he donated millions of dollars to GOP campaign committees.

But in recent years, Bloomberg has opened his wallet for Democrats. He donated more than $100 million to help Democrats in the 2018 mid-term elections.

Bloomberg could shatter campaign spending records by the March 3 Super Tuesday primaries, campaign experts said.
