From a story on politico.com by Charlie Mahtesian and Madi Alexander headlined “‘This Is a Really Big Deal’: How College Towns are Decimating the GOP”:

Spring elections in Wisconsin are typically low turnout affairs, but in April, with the nation watching the state’s bitterly contested Supreme Court race, voters turned out in record-breaking numbers.

No place was more energized to vote than Dane County, the state’s second-most populous county after Milwaukee. It’s long been a progressive stronghold thanks to the double influence of Madison, the state capital, and the University of Wisconsin, but this was something else. Turnout in Dane was higher than anywhere else in the state. And the Democratic margin of victory that delivered control of the nonpartisan court to liberals was even more lopsided than usual — and bigger than in any of the state’s other 71 counties.
