(FOX2) – As votes continue to pour in after Election Day, several key races remain to be called in Michigan on Wednesday morning.

Democrat Elissa Slotkin and Republican Mike Rogers are vying for the Senate seat left vacant by the retirement of Debbie Stabenow.

After six years representing Michigan in the House of Representatives, Slotkin is seeking a seat in the Senate. Rogers previously represented Michigan in the House from 2000 until 2014, when he announced he would not seek re-election to the 8th District.

Stabenow has held the Senate seat since 2001 and fended off Republican challenger John James by 6.5% in 2018, the closest U.S. Senate race since her first election in 2000.

The last time a Republican won the race for one of Michigan’s two U.S. Senate seats was in 1994, when Spencer Abraham defeated Democrat Bob Carr by nearly ten points. Abraham held the seat for one term before ultimately losing to Stabenow in the 2000 election.

Republican John James will defend his seat for the first time in the 2024 elections.

This election is not the first time he has faced his Democratic opponent. James defeated Carl Marlinga for the 10th seat in the House of Representatives by just 1,600 votes in 2022.

The race was extremely close two years ago, but is not seen as a toss-up in this election. The 10th District is seen as a left-leaning one, but it is still expected to be an extremely close race as Democrats have targeted it as a congressional seat that could be flipped.

Democrat Kristen McDonald Rivet and Republican Paul Junge are vying for the House seat left open by Dan Kildee’s retirement.

McDonald Rivet spent time in the Michigan Senate and has worked in state government. Junge, meanwhile, worked in the Trump administration before running against Elissa Slotkin in 2020 and Kildee in 2022.

Junge has previously run for Congress but lost the past two elections. However, Republicans see the opening as an opportunity. The district, which includes Flint, Saginaw, Midland and Bay City, as well as other communities, has become more conservative since redistricting in 2022.
