Andrew Gillum's financial disclosure form doesn't look like the paperwork of his opponents in the Florida governor's race.

Compared to former Miami Beach Mayor Philip Levine and former Congresswoman Gwen Graham, Gillum's got a couple of digits missing from the "net worth" area.

Gillum disclosed that he has a net worth of $334,200 — a tiny fraction of the eight and nine-figure net worths disclosed by Graham, the heiress to a booming family business, and Levine, a wealthy cruise industry entrepreneur. (Orlando Businessman Chris King and south Florida real estate magnate Jeff Greene, the two other Democrats seeking the governor's mansion, have not filed the financial disclosure forms necessary to qualify for the race.)

The Tallahassee Mayor and son of a bus driver and construction worker often speaks about how he's the only non-millionaire in the race for governor. The financial disclosures, on which qualified Florida candidates must disclose income, assets and liabilities, give a look at just how stark the wealth disparity is in the Florida governor's race.

Gillum disclosed that he took in about $180,000 in 2017 income — compared to $3.6 million for Levine and $870,000 for Graham. Gillum made $80,000 as mayor Tallahassee, $71,000 for his "leadership consulting" work for the firm P&P Communications, and about $26,000 working for the People for the American Way Foundation. (The Times has previously reported on how Gillum's campaign paid P&P $25,000.)

The forms are also a reminder the difficulty of running an expensive statewide campaign without significant contribution from a candidate's own bank account. Gov. Rick Scott famously poured tens of millions of his own dollars into his election and re-election efforts. King, Graham and Levine have each donated sizable figures to their campaigns this cycle. And Greene Tuesday announced he's launching a multimillion dollar ad campaign of his own.

King, Graham and Levine have also begun airing television ads. Gillum, who has struggled to fundraise outside of a few large donations from mega-donors, has yet to hit the airwaves. With no personal fortune to draw from, it will be much harder for Gillum to blast his message across Florida's spread-out media markets.

Despite the challenges, Gillum's campaign has shown signs of life recently. The candidate posted strong back-to-back debate performances last week, and on Tuesday, a poll released by Gravis Marketing showed him in the lead for the Democratic nomination. He pulled 29 percent compared to just 24 percent for Graham, 17 percent for Levine and 3 percent for King. (The survey, which interviewed 485 likely Florida general election voters, did not ask voters about Greene.)

The poll — which was connected to CATECOMM, a group that work for the Gillum campaign — is something of an outlier. Most recent surveys have shown Levine in the lead. Still, it's an encouraging result for Gillum.
