Bloomberg’s campaign is staffing up big in Florida and sees the state — with its large population of New York expats and Jewish Americans — as a top target as part of its unprecedented strategy to compete in states that start voting on Super Tuesday.

Murphy co-chairs the Blue Dog Coalition, which prioritizes fiscal restraint and national defense. She will serve as a national co-chairwoman for the Bloomberg campaign, which this week launched its “Women for Mike” effort with a big New York reception near Times Square.

“In order to win Florida you need message and machine, and I think that Mayor Bloomberg has both,” she said. “He is already making commitments to building that machine there, and I think that is critical.”

Murphy is Bloomberg’s second congressional endorsement this week, after Rep. Max Rose (D-N.Y.), whose backing was notable in part because the former New York mayor had previously donated to Rose’s opponent, then-Rep. Dan Donovan, during the GOP primary for that seat.

In a statement, Bloomberg lauded Murphy as someone who understands that dysfunction in Washington is holding the country back — as well as her own push for more gun control measures following a 2016 mass shooting in Florida that killed 49 people and wounded dozens more.

“We share a vision for breaking the gridlock in Congress, ensuring the safety of all Americans and giving them a larger voice in our future,” Bloomberg said. “After the Pulse nightclub shooting, she ran for office to bring change to Washington, including common sense gun laws — and as president, I will work closely with her to get it done.”
