U.S. Sen. David Perdue has amassed a campaign war chest of $9 million to boost his re-election bid in November, after collecting roughly $1.6 million from donors over the first three months of the year.

The Republican also raised another $800,000 between January and March for outside groups that will help his quest for a second term. He didn’t draw a Republican challenger after facing a drawn-out competition for an open seat six years ago.

Three well-known Democrats are racing to compete against him: Sarah Riggs Amico, a former candidate for lieutenant governor; Jon Ossoff, who ran for Georgia’s 6th District in 2017; and ex-Columbus Mayor Teresa Tomlinson.

The financial reports for federal candidates due Wednesday span a three-month period between Jan. 1 and the end of March, a stretch that coincided with a worsening coronavirus pandemic that drained bank accounts and sapped interest in political contests.
