Craig Gilbert writes How population growth and decline around Wisconsin are keeping the state politically balanced:
Dane County accounted for 44% of Wisconsin’s total population growth from 2010 to 2020, according to these latest numbers. The WOW [Waukesha, Ozaukee and Washington] counties accounted for 17%. And the BOW [Brown, Outagamie and Winnebago] counties accounted for 23%. Together, they generated 84% of the state’s growth over the decade.
While these three regions differ in their politics, they did have one thing in common in the 2020 election: all of them shifted away from Republican Donald Trump.
This is one of the sobering facts for Republicans in the new county-by-county population estimates for Wisconsin: of the 10 counties that added the most people over the past decade, the GOP’s performance declined in each one of them between 2016 and 2020.
Meanwhile, of the 38 mostly small Wisconsin counties where Trump gained ground in 2020, 24 of them lost population over the past decade.
….
But there are sobering facts for Democrats in the same data.
One is that ultra-blue Milwaukee, the state’s biggest county, was a population loser for the decade.
Another is that while Dane is the highest-growth county in the state, most of the other top-growing counties in Wisconsin lean Republican, which is offsetting some of Dane’s political impact. Because of their growth, some of these red counties are delivering bigger raw vote margins for Republicans even as Republicans are getting a smaller share of their vote.
For example, Trump’s point margin in Washington County dropped from 40 to 38 points between 2016 and 2020. But because the county’s total vote grew, Trump’s raw vote margin was almost 3,000 votes bigger in 2020. Something similar happened in St. Croix County in western Wisconsin.
Politically speaking, these population trends are a mixed bag. They aren’t uniformly helpful to one party or the other.
Michael LaForgia and Jennifer Valentino-DeVries report How a Genetic Trait in Black People Can Give the Police Cover (‘Sickle cell trait has been cited in dozens of police custody deaths ruled accidental or natural, even though the condition is benign on its own”):
The New York Times has found at least 46 other instances over the past 25 years in which medical examiners, law enforcement officials or defenders of accused officers pointed to the trait as a cause or major factor in deaths of Black people in custody. Fifteen such deaths have occurred since 2015.
In roughly two-thirds of the cases, the person who died had been forcefully restrained by the authorities, pepper-sprayed or shocked with stun guns. Scattered across 22 states and Puerto Rico, in big cities and small towns, the determinations on sickle cell trait often created enough doubt for officers to avert criminal or civil penalties, The Times found.
….
In three cases, deaths linked to sickle cell trait that were deemed natural or of indeterminate cause were later ruled homicides — as occurred when Martin Lee Anderson, 14, died at the hands of his jailers at a northwest Florida juvenile detention camp in January 2006.
“You can’t put the blame on sickle cell trait when there is a knee on the neck or when there is a chokehold or the person is hogtied,” said Dr. Roger A. Mitchell Jr., the former chief medical examiner for the District of Columbia and now chairman of pathology at the Howard University College of Medicine. “You can’t say, ‘Well, he’s fragile.’ No, that becomes a homicide.”
