Considering the recent pattern of American politics, the Republicans’ choice to hold their convention this July in Milwaukee, Wisconsin, is no surprise. Barack Obama easily won the state twice, but in the other four presidential contests this century Wisconsin was decided by less than 1% of the vote. Hillary Clinton, who did not even campaign there in 2016 against Donald Trump, lost the state by 23,000 votes. In 2020 Joe Biden did not repeat her mistake. The Democrats planned their convention for Milwaukee, before covid-19 intervened, and in the end he carried the state, though by just 21,000 votes out of more than 3.2m. Wisconsin is among the handful of swing states this year.
