Chuck Grassley, a Republican seeking an eighth term in the U.S. Senate, is concerned that science is becoming politicized, but fears any official responsible for stopping it could become politicized themselves.

Michael Franken, Grassley’s Democratic challenger, says the government should dismantle giant agricultural monopolies and promote regional food hubs to make Iowa farms more sustainable.

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.

New laws enacted by Republican legislators and Governor Kim Reynolds succeeded in limiting third-party competition for Iowa’s state and federal offices.

According to the general election candidate list published by the Iowa Secretary of State’s office on March 21, only one minor-party candidate qualified for a federal office this year: Bryan Jack Holder, who is running in the fourth Congressional district. Libertarians are fielding candidates for governor and lieutenant governor: Rick Stewart and Marco Battaglia. In 2018, Libertarian candidates were on the ballot for all of Iowa’s statewide and federal offices.

No independent candidate filed for any federal or statewide office in Iowa this year. For most of the last decade’s elections, independent candidates were on the ballot for several of those offices.

Only two candidates not representing a major party filed for any of the the 34 Iowa Senate seats on the ballot in 2022; both are running in Senate district 17. Across the 100 Iowa House races, only three Libertarian candidates and four independents will appear on the November ballot.

Before Republicans passed new restrictions in 2019 and 2021, Iowa voters were able to choose candidates not representing either major party in more elections.

The filing period for general election candidates in Iowa closed last Friday, so it’s a good time to review where candidates not representing either the Democratic or Republican Party are running for office. The full candidate list is on the Iowa Secretary of State’s website (pdf(. After the jump I discuss all the federal, statewide, and state legislative races including at least one independent or minor-party candidate. Where possible, I’ve linked to campaign websites, so you can learn more about the candidates and their priorities.

Rarely has any Iowa election been affected by an independent or third-party candidate on the ballot. Arguably, the most recent case may have been the 2010 election in Iowa’s first Congressional district. Final results showed that Democratic incumbent Bruce Braley defeated Republican challenger Ben Lange by 4,209 votes, while conservative candidates Rob Petsche and Jason Faulkner drew 4,087 votes and 2,092 votes, respectively.

Any comments about Iowa’s 2014 elections are welcome in this thread.
