The race for the U.S. Senate seat in Arizona will be one of the most highly watched matches of the 2024 election cycle nationwide.

Looking to replace outgoing independent Sen. Kyrsten Sinema, six people have made the primary ballot in three parties. Ruben Gallego, the Democratic congressman running for the seat, will face no primary competition, while three people — Kari Lake, Mark Lamb and Elizabeth Reye — will battle for the Republican nomination, and two more will seek the Green Party nomination.

Ruben Gallego

Ruben Gallego currently serves in the U.S. Congress representing Arizona’s 3rd District. He was elected to the seat in 2014.

A Democrat, Gallego served in the Arizona House of Representatives prior to being elected to Congress.

Originally from Chicago, Gallego graduated from Harvard University with a degree in international relations before joining the U.S. Marine Corps. He served a tour of duty in Iraq during 2005.

Following his military service, Gallego was motivated to get involved in politics to help fellow veterans. He served as chief of staff for Phoenix City Councilman Michael Nowakaowski and was vice chair of the

Arizona Democratic Party before running for office.

Gallego has a list of policy positions he is looking at, from running as a pro-choice candidate on abortion rights to bringing more jobs to Arizona while protecting the state’s public lands and natural resources.

Arturo Hernandez

Arturo Hernandez does not have information available online about his candidacy. Forms filed with the Federal Election Commission indicate he is a Yuma resident running for the nomination of the Green Party.

The Arizona Green Party has said Hernandez has not been a part of the local party up to this point.

After serving a church mission in Buenos Aires, Argentina, Lamb moved back to Arizona with his wife and the couple had five children. He started as a small business owner before deciding to run for office.

Lamb’s law enforcement career began with the Salt River Pima-Maricopa Indian Community where he rose through the ranks to become a detective.
