LANSING, Mich. (AP) — Key nominations are at stake for governor, U.S. Senate and other offices in Michigan’s primary today.

Voters will choose would-be successors to second-term Republican Gov. Rick Snyder, who cannot run again due to term limits, and a Republican nominee to face third-term Democratic Sen. Debbie Stabenow. The primary also is when the next congressman or congresswoman will effectively be chosen in two solidly Democratic U.S. House seats opening due to retirements.

Dickinson County voters will see several millage renewals on the ballot, including for the senior centers, enhanced 911 and the library. A new millage for the Norway Senior Center will be voted on by City of Norway, and Norway and Waucedah townships only.

Also in Dickinson County, incumbent District 1 Dickinson County Commissioner Joe Stevens will face a challenge from Steven Mulka on the Republican side of the ticket. In District 4, incumbent commissioner Henry Wender is up against Wallace Townsend for the Republican nomination.

Ed McBroom of Vulcan, and Mike Carey of Crystal Falls are seeking the Republican spot in Michigan Senate’s 38th District seat, which encompasses much of the Upper Peninsula, including Alger, Baraga, Delta, Dickinson, Gogebic, Houghton, Iron, Keweenaw, Marquette, Menominee, Ontonagon and Schoolcraft counties

Some of the state races include:

GOVERNOR

Former legislative leader and establishment favorite Gretchen Whitmer is facing two political newcomers for the Democratic nomination — former Detroit health director Abdul El-Sayed and chemical-testing businessman Shri Thanedar.

In the Republican contest , Attorney General Bill Schuette — a longtime veteran of state politics who secured an endorsement from President Donald Trump early — is going against Lt. Gov. Brian Calley, conservative state Sen. Patrick Colbeck and Dr. Jim Hines, an obstetrician-gynecologist who has never held elective office.

SENATE

Two Detroit-area businessmen who have never held elective office, John James and Sandy Pensler, are vying to square off against Stabenow. James, an African-American West Point graduate, flew Apache helicopters in combat and led two platoons during the Iraq War. The Ivy League-educated Pensler is emphasizing his experience in the business world, where he advised large corporations on restructuring.

HOW TO VOTE

Polls will be open from 7 a.m. to 8 p.m. Voters must have a photo ID or sign an affidavit. Absentee voters have until 8 p.m. today to return their ballot to the clerk’s office.
