The 9th district is based in Northwest Ohio, including Toledo and the western Lake Erie coast. The incumbent was Democrat Marcy Kaptur, who was re-elected with 63.1% of the vote in 2020.[1] She was running for re-election.
This district was included on the list of Democratic-held seats the National Republican Congressional Committee targeted in 2022.[81] The seat was significantly changed due to redistricting, losing all of its territory in Lorain and Cuyahoga counties while picking up more territory in northwest Ohio. This turned the district from a safely Democratic seat to a competitive one.
During the campaign, the Associated Press reported that Majewski may have falsified his service record and lied about serving in Afghanistan.[82]
Kaptur was re-elected in 2022; her win was the second largest overperformance by a Democratic candidate of their district's baseline partnership in the 2022 election, in part due to accusations that Majewski stole valor.[31][83][84]

J.R. Majewski ran on his military experience, claiming to have been a combat veteran deployed to Afghanistan. A public records request by the Associated Press showed that Majewski worked for six months loading planes in Qatar but did not receive any medals given to those who served in Afghanistan, and the campaign did not confirm if he was ever there.[100]
However, in August 2023, the United States Air Force added the Global War on Terrorism Expeditionary Medal to Majewski's record and issued a corrected discharge form. Majewski said that the correction had "vindicated" him, after questions about his military service arose in the media during the 2022 general election. According to The Toledo Blade, Majewski said he did in fact deliver cargo to Afghanistan, among other locations, and that the military still referred to him as a combat veteran even though "not all of us were kicking in doors and shooting people".[101]
Although the district would have gone for Donald Trump by 2.9 points, Kaptur easily won re-election. Kaptur won Erie County, which Trump won by over 10 points, and was the only Democrat to win this county in this election cycle. Her performance was the largest overperformance of the partisan baseline by a Democratic candidate during the 2022 midterms.[83]
