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. Wisconsin utilizes an open primary system; registered voters do not have to be members of a party to vote in that party's primary.[10]
For information about which offices are nominated via primary election, see this article.
Poll times
In Wisconsin, polls are open from 7 a.m. to 8 p.m. Central Time. Anyone in line when the polls close must be allowed to vote.[11]
Registration requirements

To register to vote in Wisconsin, one must be a citizen of the United States and a resident of Wisconsin at their current address for at least 28 days before the election. A voter must be at least 18 years of age by Election Day.[12]
Prospective voters can register online or by mailing a form to their municipal clerk. If registering by mail, the application must be postmarked no later than 20 days before the election.[13] Voters must also register online by the 20th day before the election. In-person registration at a municipal clerk's office must be completed by 5 p.m. or the close of business on the Friday before Election Day, whichever is later. Prospective voters can also register at their polling place on Election Day using same-day voter registration. Voters must provide proof of residence when registering to vote.[12]

Same-day registration
Wisconsin allows same-day voter registration.[15]
Residency requirements
Wisconsin law requires 28 days of residency in a precinct before a person may vote.[12]
Verification of citizenship
Wisconsin does not require proof of citizenship for voter registration. An individual must attest that they are a U.S. citizen when registering to vote. According to the state's voter registration application, a voter who provides false information "may be subject to fine or imprisonment under State and Federal laws."[16]
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.[17] Six states — Alabama, Arizona, Kansas, Louisiana, New Hampshire, and Wyoming — have laws requiring individuals provide proof of citizenship at the time of voter registration, whether in effect or not. Two states, Georgia and Mississippi, require a person provide proof of citizenship if their citizenship status cannot be verified by other means. 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.

The site My Vote, run by the Wisconsin Election Commission, allows residents to check their voter registration status online.

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. Alabama, Mississippi, and New Hampshire do not offer no-excuse early voting.

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."
