Primary elections—in which registered voters select a candidate whom they believe should run on the party's ticket in the general election—can reflect internal conflict over the direction of a party.
Heading into the 2018 election, the Republican Party's legislative record during Donald Trump’s presidency figured into several Republican primaries. This record included the passage of major tax legislation in December 2017 and the confirmation of federal judges. It also included a $1.3 trillion omnibus spending bill in March 2018, which Trump opposed, and unsuccessful efforts to repeal and replace the Affordable Care Act.[1][2]
Trump, himself, also played a role in Republican primaries. His approval rating reached 90% in June among self-described Republicans, according to a Gallup survey.[3] Many Republican candidates campaigned on their support for Trump, and negative ads accusing opponents of criticizing the president were common.[4][5][6] A May report found Trump's name or image had appeared in 37% of all Republican campaign ads at that point in 2018.[7]

Voter information
How the primary works
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. In Iowa, state law provides for a closed primary where every voter must be affiliated with a party in order to participate in its primary. However, a voter can change his or her political party affiliation on the day of the primary.[10][11]
For information about which offices are nominated via primary election, see this article.
Poll times
In Iowa, all polls are open from 7:00 a.m. to 8:00 p.m. Central Time. An individual who is in line at the time polls close must be allowed to vote.[12][13]
Registration requirements

To vote in Iowa, one must be a United States citizen, a resident of Iowa, and at least 18 years old by Election Day. A voter that is 17 years old may participate in a primary election if they will be 18 by the time of the next general election. The deadline to register is 15 days prior to the election but registration is permitted on Election Day with proof of identification.Iowans may register online or by completing a form and returning to their county auditor’s office by mail or in person.[14][15]

Residency requirements
To register to vote in Iowa, you must be a resident of the state. State law does not specify a length of time for which you must have been a resident to be eligible.
Verification of citizenship
Iowa does not require proof of citizenship for voter registration. An individual applying to register to vote must attest that they are a U.S. citizen under penalty of perjury.[17]
All 49 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment.[18] Seven states — Alabama, Arizona, Georgia, Kansas, Louisiana, New Hampshire, and Wyoming — have laws requiring verification of citizenship at the time of voter registration, whether in effect or not. One state, Ohio, requires proof of citizenship only when registering to vote at a Bureau of Motor Vehicles facility. In three states — California, Maryland, and Vermont — at least one local jurisdiction allows noncitizens to vote in some local elections. Noncitizens registering to vote in those elections must complete a voter registration application provided by the local jurisdiction and are not eligible to register as state or federal voters.
Verifying your registration
The Iowa secretary of state’s office maintains a page that allows residents to check their voter registration status online.

Early voting permits citizens to cast ballots in person at a polling place prior to an election. In states that permit no-excuse early voting, a voter does not have to provide an excuse for being unable to vote on Election Day. States that allow voters to cast no-excuse absentee/mail-in ballots in person are counted as no-excuse early voting states.
Forty-seven states and the District of Columbia permit no-excuse early voting.
Absentee voting
All voters are eligible to vote absentee/by-mail in Iowa. There are no special eligibility requirements for voting absentee. To vote absentee/by-mail, a request application must be received by the county auditor between 70 days before the election and 5 p.m. on the 15th day prior to the election. Voters must include one of the following: Iowa driver's license or non-operator ID number, voter ID/verification number, or the four-digit PIN from their voter ID card. Returned absentee ballots must be received by the time polls close on Election Day in order to be counted.[22]

- ↑ Under federal law, the national mail voter registration application (a version of which is in use in all states with voter registration systems) requires applicants to indicate that they are U.S. citizens in order to complete an application to vote in state or federal elections, but does not require voters to provide documentary proof of citizenship. According to the U.S. Department of Justice, the application "may require only the minimum amount of information necessary to prevent duplicate voter registrations and permit State officials both to determine the eligibility of the applicant to vote and to administer the voting process."
