The states of Illinois, North Dakota, Florida and Michigan all began early voting on Thursday as the 2024 election continues to get underway.

Here is all the information about the elections in each state and how to vote.

Michigan shocked the country in 2016 when it backed former President Trump by 0.23 points, or a mere 10,704 votes.

Since then, the state has delivered for Democrats, with a nearly 3 point win for President Biden, the election and re-election of Governor Gretchen Whitmer, and in the last midterms, a state government trifecta.

Even so, this will be a competitive race. Recent high-quality polls have Harris ahead by 2 to 5 points; in each case within the margin of error.

Democrats do well in the southeastern part of the state, and Biden was able to win in 2020 by bringing out Black voters and gaining in the Detroit metro area. Flipping Kent County, home to Grand Rapids and a representative mix of urban, suburban, and rural vote, was also crucial to his victory. Trump will need to take it back for a statewide win in 2024.

Michigan’s population grew by 2% over the last full decade, with growth concentrated in the Grand Rapids area. Since then, the state has experienced decline, especially in Detroit.

The Great Lake State will also vote for a new senator after Democratic Sen. Debbie Stabenow decided not to run for reelection this year. House Rep. Elissa Slotkin hopes to keep the seat in Democratic hands and has an edge in this competitive race. She faces GOP candidate and former Rep. Mike Rogers.

Both the presidential and senate races are ranked Lean D on the Fox News Power Rankings.
