U.S. Rep. Jason Crow has raised more than $1 million for his 2020 re-election bid since unseating five-term Republican Mike Coffman, leaving the freshman Democrat with a hefty war chest to defend the suburban 6th Congressional District.

The Aurora attorney and Army Ranger veteran raised $430,461 for the three-month period ending June 30, according to numbers provided to Colorado Politics.

Added to the $504,317 Crow reported raising in the year's first quarter and the roughly $90,000 he pulled in between the election and Dec. 31, that puts Crow's fundraising total at $1,026,000.

His campaign said Crow had about $800,000 in the bank at the end of the most recent quarter.

“Our strong fundraising numbers reflect more than our campaign’s momentum," Crow told Colorado Politics in a statement. "It’s proof that Coloradans share our vision for a Washington where our representatives work for the people, not corporate special interests.”

One of the first congressional challengers to decline contributions from corporate PACs during the last cycle, Crow has said he plans to stick to that pledge this time around.

About 80% of this quarter's donations were under $100, a campaign spokeswoman said.

Republicans have yet to settle on a candidate in the perennial battleground district, which covers Aurora and parts of Adams, Arapahoe and Douglas counties.

So far, just one GOP candidate has filed to take on Crow — motivational speaker and Uber driver Casper Stockham, who lost back-to-back attempts to unseat U.S. Rep. Diana DeGette in the heavily Democratic 1st Congressional District.

Former state Rep. Phil Covarrubias, who lost his Adams County-based legislative seat last year in a Republican primary, told Colorado Politics in May he was "about a foot away" from declaring a run against Crow, but in June he filed to run for Adams County commissioner.

UPDATE: After floating a 2020 run against Crow this spring, former state Rep. Phil Covarrubias, a Republican, filed in June to run for Adams County commissioner.
