Republican Judson Hill raised nearly $500,000 in his campaign to represent a suburban Atlanta district in Congress that could be an early test of Donald Trump's popularity.

The former state senator reported raising $473,000 and had $113,000 in his campaign coffers in the final stretch of the April 18 special election to succeed Rep. Tom Price.

As the first Republican to enter the contest - he joined shortly after Trump named Price his health secretary -  Hill had more time to raise cash than other top contenders. His campaign hopes his fundraising haul sends a message to conservatives hoping to avoid an embarrassment in a district held by the GOP since Jimmy Carter was in the White House.

The contest to represent the district, which spans from east Cobb to north DeKalb, drew 18 candidates who will all be on the same ballot regardless of party. But Republicans are dueling over what appears to be one spot in a June 20 runoff against Democrat Jon Ossoff.

With his "Make Trump Furious" campaign, Ossoff has emerged as the unquestioned leader in the jumbled field. He's raised at least $3.5 million, captured celebrity endorsements and enlisted thousands of volunteers. He openly talks of winning the race outright by capturing a majority of votes in April to avoid a June 20 runoff.

Financial disclosures are due late next week, and the details of Hill’s donors were not immediately available.
