The Democratic National Committee had its worst May since 2003, raising just $4.3 million dollars as it struggles to rebound from a series of election defeats, according to Federal Election Commission data.

The last time May fundraising was lower was in 2003, when the DNC raised just $2.7 million.

In contrast, the Republican National Committee raised more than double, notching $10.8 million in May, a record-high amount for an off-year.

DNC Chairman Tom Perez defended the party's fundraising in April, noting that he had just taken over at the helm of the organization.

In an NBC interview, Perez was asked about his progress on his goal of doubling the DNC's budget from $50 million to $100 million in 2017.

"Well again, I got there on March 1. And so, I was the first to say, 'We have a lot of rebuilding to do,'" Perez told NBC's Hallie Jackson.

April brought in $4.9 million, making it the worst fundraising April for the DNC since 2009.

Fundraising woes aren't the DNC's only concern.

Despite a cash advantage, Democrat Jon Ossoff lost Tuesday's special election for a Georgia House seat in the most expensive race in history, costing at least $40 million dollars.
