DES MOINES, Iowa -- Iowans will head to the polls Tuesday to cast their ballots in the primary election, with plenty of candidates looking for their vote.

In Iowa's fourth congressional district, State Senator Rick Bertrand is looking to make history. He is challenging incumbent Steve King, who is up for an eighth term.

No Iowa congressman has lost a primary in 68 years.

Also, three democrats will vie for the nomination in the third congressional district. The winner will go up against Republican David Young in November. Young is in his first term of office.

In addition, possibly the most watched race will be for the Democratic nomination and a chance to challenge Senator Chuck Grassley. Four candidates will be looking to win the nomination Tuesday. The winner will go against Grassley in November. The Senior Senator has been in public office for nearly 60 years.

Dr. Rachel Paine Caufield, a professor at Drake University, says this election is unique for Grassley.

“Grassley is more vulnerable this time around then he has been in several cycles now. He is in the national spotlight and clearly the democrats are taking advantage of that, particularly Patty Judge. Come November, this could be a tighter race for him than he`s had in a long time. Ultimately incumbents are so favored in this process that I feel he has reason to feel good about it,” said Caufield.

How to Vote

Polls open statewide at 7 a.m. and close at 9 p.m. in all precincts on Tuesday.

Based on your address, the Iowa State Secretary of State's website shows you where to vote. Twenty-nine polling locations have changed since the 2014 General Election.

If you have moved to Iowa from another state or to a different county in Iowa, you are to register in your new county 10 days before general elections and 11 days before all other elections. If you miss the pre-registration deadline, Election Day registration is available.

Absentee ballots should have been postmarked by June 6 by the U.S. Post Office in order for them to count.

If you have any questions about voting in your county, contact your county auditor.

About the Primary Election

“Primary elections require voters to declare a party affiliation,” said Polk County Auditor Jamie Fitzgerald. “If a voter is not registered with the party whose ballot they wish to vote they can make that change at our precinct polling place on Election Day.”

Under Iowa law, voters must declare themselves as a Democrat or Republican in order to vote in the primary. Thousands of voters changed their political parties in order to participate in the Iowa Caucuses, according to a release by the Polk County Auditor's Office.
