Iowa’s filing period for the 2022 general election closed on August 27 with no third-party candidate qualified for the ballot in any federal race, or any statewide race other than for governor and lieutenant governor.

The landscape could hardly be more different from four years ago, when the Libertarian Party of Iowa fielded a full slate of federal and statewide candidates, and no-party candidates also competed in three of the four U.S. House districts.

The lack of a third-party presence could be important if any of Iowa’s Congressional or statewide elections are close contests.

The Cook Political Report changed its rating on Iowa’s fourth Congressional district today from “likely” to “lean” Republican. Although eight-term U.S. Representative Steve King carried this R+11 district by more than 20 points in 2016, several factors make a winning path for Democratic challenger J.D. Scholten seem more plausible than a few months ago, when forecasters moved IA-04 from “safe” to “likely” Republican.

Change Research announced last night that its new survey showed King leading Scholten by just 45 percent to 44 percent. The incumbent quickly released results from an internal poll by WPA Intelligence, showing King ahead by 52 percent to 34 percent, with 11 percent undecided and 3 percent inclined to support a third-party candidate.

FiveThirtyEight.com still gives King a 5 in 6 chance of winning a ninth term, but he could have set himself up much better for next Tuesday. Consider:

Eight-term U.S. Representative Steve King is polling below 50 percent and only six points ahead of his Democratic challenger J.D. Scholten, according to a recent survey commissioned by Scholten’s campaign. Expedition Strategies surveyed 380 “likely 2018 general election voters” in Iowa’s fourth Congressional district between September 5 and September 9 and found 43 percent supported King, 37 percent Scholten. Another 15 percent were undecided, 4 percent backed Libertarian Charles Aldrich, and 2 percent Edward Peterson. The poll’s margin of error was plus or minus 5 percent.

For the first time, at least one third-party candidate has qualified for every Congressional or statewide office in Iowa. Although third parties haven’t traditionally fared well in Iowa, Libertarians had their best showing ever here in 2016 and have nominated a record number of candidates for this November. Since several U.S. House or statewide races could be very close, even a small percentage of the vote for candidates other than the Democratic or Republican contenders could become significant.

With the filing period for Iowa’s general election ballot closed as of 5:00 pm on August 25, it’s time for an overview of the landscape. The full candidate list is posted on the Iowa Secretary of State’s website. UPDATE: John Deeth notes that candidates may have filed on the last day, which wouldn’t be reflected on the version currently posted online. I will update as needed; the key point is that there will be no statewide or Congressional races in Iowa this year with only Republican and Democratic options on the ballot. SECOND UPDATE: The Secretary of State’s office uploaded an amended candidate list on August 27. No new candidates filed for statewide office, but one additional person qualified for the ballot in the fourth Congressional district. Scroll down for further details.

Representative Steve King is making national news again, this time for re-tweeting a neo-Nazi British politician. King’s long had a thing for European right-wingers who stir up racist fear about non-white immigration. As usual, no House Republicans are calling for King to resign, nor has any prominent Iowa Republican denounced the sentiments. King repeated his warning about immigration this morning.

J.D. Scholten won the Democratic nomination in Iowa’s fourth Congressional district convincingly with 51 percent of the vote in a three-way field. He will be the underdog in November. All the major election forecasters rate this district as safe for Republicans, since King won more than 60 percent of the vote in 2014 and 2016.

On the other hand, a few months ago, a Democrat won a special election in a Pennsylvania U.S. House district with a partisan voting index of R+11–the same as IA-04. More recently, a Republican barely won a special election in an R+13 Arizona House district.

Here’s what Scholten needs to pull off what would be a huge upset:

The Libertarian Party of Iowa has full political party status for the first time this election cycle, thanks to a record-breaking showing here by presidential candidate Gary Johnson in 2016. But Libertarians are far from fielding anything close to a full slate of candidates for state offices.

Promising to offer voters “a Republican alternative that is truly reflective of Iowa and the values we cherish,” Cyndi Hanson announced on December 5 that she will seek the GOP nomination in the fourth Congressional district.
