Early voting begins in Michigan and Illinois.

Michigan and some Illinois residents can start voting Thursday for the Nov. 8 midterm elections as both states open up for early in-person voting.

Voting is also underway in some form in six other states: South Dakota, Wyoming, Minnesota, Virginia, New Jersey and Vermont.

In Michigan, three Republicans backed by former President Donald J. Trump will face off against three incumbent Democrats holding statewide office. Governor Gretchen Whitmer takes on Tudor Dixon, a conservative media personality; Secretary of State Jocelyn Benson confronts Kristina Karamo; and Attorney General Dana Nessel is being challenged by Matt DePerno. Both Karamo and DePerno have been outspoken defenders of Trump’s election lies.

Michigan voters will also decide on a ballot initiative that would add legal protections for abortion to the state constitution.

Thursday is also when Michigan and many Illinois counties will begin sending absentee and mail-in ballots to registered voters who have requested them.

Michigan lawmakers on Wednesday passed a bill that will allow local election officials to start processing mail-in and absentee ballots two days before Election Day. While they won’t be able to start counting ballots until Nov. 8, the extra processing time is intended to help ease the burden on officials on Election Day, which could speed up the release of results. The change was part of a series of election laws passed just before early voting began, and after an agreement was reached with the governor’s office, the Detroit Free Press informed.

In Illinois, where county officials can choose when to open early voting locations, Chicagoans will have to wait: Cook County, which encompasses the city, won’t open early voting until Oct. 7. Offices on Thursday.

South Dakota, Wyoming and Minnesota opened early voting in person on September 23 and sent ballots by mail. In those states, residents can choose to vote by mail without giving an excuse or reason why they cannot go to the polls.

On September 24, Virginia and New Jersey began accepting some ballots. In Virginia, that’s when voters can begin casting their ballots in person at county record offices. In New Jersey, early voting in person will not begin until October 29, but early voting by mail began on September 24.

Elections officials in Vermont are sending ballots to the state’s roughly 440,000 active voters, where one Senate seat and the state’s only House seat are up for grabs. All ballots must be mailed in by Friday and received by October 10. Voters who prefer to vote in person may do so at their city offices during normal business hours.
