ST. PETERSBURG — The scavengers descended Wednesday, hunting for whatever was left.

A collector of political memorabilia made off with buttons and a stack of “I Like Mike” placards.

An activist scored some lawn signs. He planned to cover up the 2020 presidential slogans with anti-Trump messages for weekly rallies outside St. Petersburg City Hall.

Posted by the door was a confident message: “DELIVERING RESULTS." Except that didn’t happen on Super Tuesday. Instead, former New York City mayor Michael Bloomberg’s reported $600 million campaign for the Democratic presidential nomination flamed out.

This was one of 150 Bloomberg campaign offices that sprouted up over the past three months as the billionaire hoped to swoop in and clinch the Democratic nomination at the last minute. Located next to a dessert bar in the Grand Central District, the windows were festooned with “Mike 2020 Florida” signs.

It lasted one month.

In Florida alone, Politico reported that Bloomberg poured nearly $50 million of his personal fortune into buying ads.

In St. Petersburg, hours after Bloomberg dropped out of the race, all that was left of that was a nearly-empty office decorated with balloons and posters extolling the candidate’s supposedly broad appeal: “Ask about Mike’s climate plan,” “Mike Supports the Arts," “Women for Mike," “St. Pete Mike,” “Mike’s education plans make sense 4 all."

Folding tables recently used for phone banking and voter registration were scattered with Clorox wipes and tissues. A few boxes of LaCroix sparkling water and Ring Pops sat next to a coffee machine near the front. A miniature Robert Mueller action figure peeked out from a corner by the window.

A campaign staffer declined to talk to a Tampa Bay Times reporter. Nor did the staffer have a business card to hand over — the office hadn’t been open long enough, she said.

Hours later, the office was packed up and locked.

Bloomberg joined the Democratic primary race in November as a late entry, framing himself as a moderate bulwark against the party’s progressive wing. He touted his limitless campaign budget and strong record on gun control and climate change. But at the debates he stumbled over criticism of his criminal justice record and his treatment of women. U.S. Sen. Elizabeth Warren, who is still running, went after the former mayor particularly hard.

Park Chapman, a 66-year-old Bloomberg volunteer, said he was attracted by the candidate’s deep experience both as a businessman and as mayor of a major city.

But Chapman’s larger goal is to beat Trump in the general election, and that’s not going to stop. Now he plans to start door-knocking for former Vice President Joe Biden, who has yet to open any field offices in Florida.

“I hope this office stays open and we keep up the fight,” he said gesturing towards the windows, hoping it might soon have Biden placards posted on the windows.

So far, the future of the St. Petersburg office remains undisclosed. After failing to win any of Super Tuesday’s 14 states (he did win American Samoa, though) Bloomberg threw his support behind Biden.

A Bloomberg Florida spokeswoman said she no updates to offer as to future plans for the office.
