DES MOINES, Iowa (AP) — Republicans represent all four of Iowa’s congressional districts, but Democrats are hopeful about their chances in Tuesday’s general election.

Two of the districts are considered especially competitive, including the 1st District in southeast Iowa and the 3rd District in central and southern Iowa. Republicans are expected to more easily retain control in the 2nd District in northeast Iowa and in the largely rural Fourth District in western Iowa.

In the 1st district, incumbent Republican Representative Mariannette Miller-Meeks will seek his third term in the U.S. House of Representatives when he faces the same Democrat he defeated in 2022. In that race, Miller-Meeks led Democrat Christina Bohannan by about 7 percentage points, a much larger gap than her six vote margin in 2020 over Democrat Rita Hart.

In her campaign, Bohannan, a law professor and former lawmaker at the University of Iowa, emphasized her support for abortion rights at a time when Iowa Republicans have changed the law to ban abortions in most circumstances. He also called for reducing the costs of a variety of goods and services, including food, gasoline and housing.

Miller-Meeks, a former ophthalmologist, opposes abortion rights and supported a bill seeking a national ban on abortion after 15 weeks that would have allowed states to impose even stricter limits. He has also said he wants to help reduce inflation and improve the economy, and supports lowering the price of prescription drugs and over-the-counter oral contraceptives.

The 3rd District, which includes much of the Des Moines metropolitan area, is also considered competitive with challenges from Democrat Lanon Baccam. current Republican Zach Nunn. Both candidates have military experience, as Baccam served in the Iowa National Guard and was deployed to Afghanistan. Nunn served as an Air Force pilot and served three tours in the Middle East. He was promoted to Air Force colonel in June.

Like other House elections, abortion has been a key issue, and Baccam noted Nunn’s opposition to abortion rights. Baccam said he would vote to restore the national right to abortion that ended when the U.S. Supreme Court overturned Roe v. Wade in 2022.

Nunn said that although she opposes abortion rights and has voted for severe abortion restrictions in Iowa, she does not support a nationwide abortion ban.

Both candidates have promised to support efforts to make Congress less dysfunctional and more focused on solving problems. Nunn also highlights the need to reduce illegal border crossings, and Baccam calls for improving the economy and creating more jobs for the middle class.

In the 2nd Congressional District, Republican Rep. Ashley Hinson He will seek a third term against Democrat Sarah Corkery.

Hinson, a former KCRG-TV news anchor, said her main issue is strengthening the country’s southern border. Corkery, a community activist, said her main issue is restoring abortion rights.

Jody Puffett, an independent candidate, is also running.

Incumbent Republican Rep. Randy Feenstra is seeking a third term in the sprawling 4th District, made up of 36 of Iowa’s 99 counties. He will face Democrat Ryan Melton.

Republicans have a large advantage among registered voters in the district and typically win general elections by more than 20 percentage points.
