Iowa House and Senate

Iowans will also be picking state lawmakers to represent them.

All 100 Iowa House seats are up for two-year terms, and 34 of the state's 50 Senate seats are on the ballot this year for four-year terms.

Republicans now hold a 60-40 advantage over Democrats in the House and a 32-18 majority in the Senate.

This year will see significant turnover for lawmakers after last year's redistricting process changed the legislative district boundaries to account for changes in population. Many lawmakers decided to retire or move, and some face challenges from political newcomers or fellow incumbents.

Iowa county offices

A range of county offices will appear on Iowans' ballots, including races for county supervisor, county attorney, treasurer and recorder.

In Polk County, the only contested race among those is for county attorney, where Democrat Kimberly Graham and Republican Allan Richards are facing off to replace retiring 32-year-incumbent John Sarcone.

Iowans will also see nonpartisan county races for offices like county hospital trustee, soil and water commissioner and county agricultural extension council.

Polk County has six candidates running for three positions on Broadlawns Medical Center's Board of Trustees. Broadlawns is a Des Moines-based public hospital funded by Polk County taxpayer dollars.

Judicial retention elections

In Iowa, judges and justices are appointed by the governor. But they face periodic retention elections where the public can vote on whether they should remain on the bench.

This year, voters will have the choice to retain or dismiss two Supreme Court justices, two appellate judges and 61 district-level judges across the state.

The state judicial branch describes retention elections as "intended to focus on the professional competency of Iowa's judges," rather than as a referendum on any particular ruling.

'Keep and bear arms' Iowa constitutional amendment

Voters have a rare chance this year to decide whether to amend the Iowa Constitution to add the right "to keep and bear arms."

The language of the proposal goes beyond the protections contained in the U.S. Constitution's Second Amendment.

Supporters say the amendment is necessary to protect Iowans' rights from infringement, while opponents say passing the amendment would make it easier to strike down existing gun laws and make it harder to pass new regulations.

The language of the proposed amendment states: "The right of the people to keep and bear arms shall not be infringed. The sovereign state of Iowa affirms and recognizes this right to be a fundamental individual right. Any and all restrictions of this right shall be subject to strict scrutiny."

If a majority of voters approve the amendment, it will be added to the state's constitution.
