The Florida professor challenging Democratic National Committee Chairwoman Debbie Wasserman Schultz for her congressional seat posted a strong first fundraising quarter, raising $550,000.

Tim Canova's haul came from 15,295 donnations averaging less than $20, according to figures released Monday morning by the campaign.

"Our campaign has been met with incredible enthusiasm,” Canova said in a statement released by his campaign. “There is an intense desire in South Florida, as there is around the country, to end politics as usual and elect a representative who will put the people first, not big Wall Street banks and giant companies."

The first quarter haul shows that Wasserman Schultz will likely be facing a well-funded opponent in her first primary challenge since her election in 2004. She ended 2015 with just $468,000 in her campaign account and has not yet reported her first-quarter totals, but is expected to flex her fundraising muscle during the run-up to the primary.

President Obama took the rare step last week of endorsing Wasserman Schultz ahead of that primary election, a notable decision by the president to wade into party politics.

But numbers released by Canova’s campaign implicitly suggested that move may have helped his fundraising — almost $100,000 of his donations came in the last four days of the quarter, after Obama’s endorsement.

Canova has endorsed Sanders and is trying to run with a similar populist streak as the Vermont senator. And Canova also has the backing of the National Nurses United super-PAC, the group that has already spent more than $1 million to help Sanders.

The district is leans strongly blue, so the primary will likely be the only competitive obstacle for Wasserman Schultz to keep her seat.
