Thursday's reports confirm what Scholten said in the final days of the campaign -- a flood of money from out-of-state donors flowed into his campaign as there was a growing perceived chance of him beating the eight-term Republican incumbent.

During the closing days, Scholten tweeted, "Thank you to everyone who has become a part of this incredible movement. In a little over 24 hours, we've received over $350,000 from over 7,500 individuals and signed up dozens of new volunteers."

The surge came as King found himself forced to defend his remarks on race and support for political candidates and parties with white supremacy ties.

Counting the report filed this week, Scholten, a former paralegal and professional baseball player from Sioux City, outraised King for a fifth straight quarter.

The latest FEC report shows Scholten ending the period with $122,629 in cash, after paying his expenses. King had $58,715 in cash on hand.

Scholten has not ruled out a rematch, and King has left little doubt he will seek another two-term term.
