So, a bit dicey to do this, but what the heck.
Per VoteHub, through yesterday, 2,197,855 people have already voted in Michigan. IF that poll is right, that would mean the total banked votes so far should look like this:
Harris 1,340,692
Trump. 769,249
Others 87,914
In 2020, 5,547,186 Michiganders voted in the presidential election, representing turnout of 74% of registered voters that year.
In 2016, Michigan turnout was only 64.59%.
In 2024, there are 7,263,931 registered voters. If we see 2020 turnout again, a modern record, we would expect 5,375,308 votes to be cast. In that case, the early votes to date would represent 40.9% of the total.
If we have 2016 turnout, we would get 4,691,773 total votes. In that case, the early votes so far would represent 46.8% of the total votes have already been cast and Trump would need a larger margin in the remaining votes cast today through Election Day than in a 2020 turnout to come back and win.
It’s obvious but the question we won’t know until the polls close is the total turnout and without knowing the total turnout we don’t know exactly how substantial Kamala’s early vote lead really is (assuming the polling about banked votes is accurate and still subject to the margin of error if so).
