Are COVID Deaths Changing The Electorate? Wisconsin Edition

I just wrote about a detailed calculation of COVID deaths and their potential electoral impact in Georgia, my home state. One factor that causes COVID deaths to have little political impact in Georgia: the state has a large black population which is disproportionately impacted by COVID, and this balances out deaths (politically speaking) among the older white population.

What about if we look at a swing state like Wisconsin, which is 87% white per the Census Bureau?

White deaths roughly approximate the white share of total population in Wisconsin.

This ought to mean that COVID would push the Wisconsin electorate leftward, correct?

Here are 2020 exit poll results for white voters in Wisconsin, and 2020 exit poll results for black voters in the Midwest (black Wisconsin voters weren’t available as a subset):

President Biden won Wisconsin precisely because he lost the older white vote by a relatively small margin.

Let’s do some simple math:

8064 deaths * 86.5% white = 6975 deaths

6975 deaths * (10% Trump margin amongst age groups at risk) = 698 net loss in Trump voters

8064 deaths * 7.7% black = 621 deaths

621 deaths * (62% Biden margin among black voters in Midwest) = 385 net loss in Biden voters

The Wisconsin GOP appears to have lost 300-350 net votes due to COVID thus far. It’s possible that this understates the impact, since the white voters that died post vaccine-era are increasingly represented by GOP voters (since they are more likely to refuse vaccination). But 80% of COVID deaths in Wisconsin occurred prior to general vaccine availability (prior to 1/31/21), lowering partisan effects due to vaccine hesitancy. Even if we assume a 20% Trump margin among white voters that died post 1/31, this only increases the GOP’s net vote loss to 500 votes (add 1/5th of the white vote * additional 10% margin).

The impact of a 500 vote swing could be meaningful in states where politics is a game of inches these days – but we can’t overstate it. Voters’ overall reaction to how the pandemic has been handled is by far the larger factor in how COVID impacts American politics.
