Animated by opposition to President Donald Trump and the Republican congressional majorities, at least 162 Democratic candidates in 82 GOP-held districts have raised over $100,000 so far this year, according to a POLITICO analysis of the latest FEC data. That’s about four times as many candidates as House Democrats had at this point before the 2016 or 2014 elections, and it’s more than twice as many as Republicans had running at this point eight years ago, on the eve of capturing the House in the 2010 wave election.

Nearly three dozen Republican incumbents were outraised by Democratic challengers in the third quarter of this year – a stunning figure. Nine GOP incumbents already trail a Democratic opponent in cash on hand, increasing the likelihood that many veteran incumbents will face tough opposition for the first time in years.

The Democrats’ fundraising success, especially from a glut of candidates who have never run for office before, is unsettling to those charged with protecting the GOP majority.
