An analysis by the Los Angeles Times found that Rohrabacher raised $271,969 in the fourth quarter of 2017 and has $713,144 in cash on hand.
Democrat Harley Rouda posted the largest numbers, raising $626,254 in the fourth quarter with $833,687.51 in cash on hand. But $500,000 of that came in the form of a personal loan.
In the previous quarter, Rouda lent himself $175,000, making the total amount $675,000, according to his Federal Election Commission reports.
Similarly, Omar Siddiqui, a self-described Reagan Democrat, loaned himself $200,000 and has $458,497.66 of his own money invested in his campaign.
Other than loans, Siddiqui raised 54,194.28 in the fourth quarter and reported $540,251.21 in the bank.
Stem cell researcher Hans Keirstead raised $402,140, lending himself $165,000 and ending the quarter with $490,436 in cash on hand.
Rohrabacher’s fundraising numbers come as the Democratic Congressional Campaign Committee is targeting his district, which voted for Hillary Clinton in 2016, according to the liberal website Daily Kos Elections.
Rohrabacher has said he is running for re-election even as many of his Republican colleagues are departing the House.
