I put an asterisk next to some numbers for the third Congressional district, because the official results from 2016 do not include 5,842 absentee ballots from Dallas County. Due to an egregious oversight by staff in the county auditor’s and Secretary of State’s offices, those votes were never counted.

So Clinton and Trump should each have received some 2,500 to 3,000 additional votes in IA-03. (Democrats are more likely than Republicans to vote early.) If those numbers had been tabulated, this year’s totals for Axne and Young would have comprised a slightly lower percentage of the votes cast for their party’s last presidential nominee.

For readers who prefer tables to maps, here are the same figures:

The first and third districts were among the most competitive House races in the country. Bleeding Heartland discussed the IA-01 results in more depth here and the IA-03 results here.

Democratic challenger Abby Finkenauer and two-term Republican incumbent Rod Blum combined to spend more than $6 million in IA-01, and outside groups spent more than $3.5 million to influence the outcome. Spending by Democratic contender Cindy Axne and two-term GOP incumbent David Young exceeded $6 million, and outside groups invested another $8.7 million in the IA-03 race.

Blum and Young each ran about 5 points ahead of Trump in their districts two years ago. Young has had better constituent service, been less abrasive in public appearances, and more diligent about holding events around his district, which probably explains why he performed better this year than Blum did.

Axne and Finkenauer nearly matched Clinton’s vote totals in their districts, suggesting a strong effort to mobilize the Democratic base as well as a successful persuasion campaign with swing voters. Granted, turnout was unusually high for an Iowa midterm. Even so, about 220,000 fewer people participated statewide compared to the last general election (1,334,279 ballots cast this year, 1,553,984 votes for president in 2016).

Six-term Representative Dave Loebsack ran about 9 points ahead of Clinton in the 24 counties that make up the second district two years ago. Neither party targeted IA-02 this year, and Loebsack raised and spent more than twice as much as GOP challenger Christopher Peters. For all those reasons, it’s not surprising the incumbent was able to surpass Clinton’s result.

Representative Steve King’s slippage is notable. Two years ago, he was the only Iowan in Congress who failed to significantly outperform his party’s presidential nominee. King won his eighth term with about 61.2 percent of the vote; Trump received 60.9 percent in the 39 counties that make up IA-04.

While Blum and Young gained more than 80 percent as many votes this year as Trump won on their turf two years ago, King barely managed two-thirds of Trump’s total. Even in Iowa’s most conservative district, voters are losing patience with a representative who often makes national news with racist remarks but doesn’t put in the legwork at home.

J.D. Scholten gave King the scare of his political life by running a phenomenal campaign, with a relatable message and at least three events in every county. He also out-raised and out-spent the incumbent. Few outside groups got involved in the IA-04 race, but most of the independent expenditures opposed King.

Until this summer, few political junkies saw IA-04 as potentially competitive. Major forecasters viewed the race as “likely Republican” until the final week. But if Scholten decides to take another crack at this district, he will instantly be taken seriously. He’s not ruling anything out.

Worth noting: Scholten’s mentor Tom Harkin lost his first Congressional race but beat the Republican incumbent in a rematch two years later.

Any comments about this year’s U.S. House elections are welcome in this thread.
