evidence: During the 2020 election, Hudson — a city nestled on the banks of the St. Croix River that separates Wisconsin from Minnesota — favored Trump over Biden by a slim 155 votes. Almost twice as many Hudson voters, 308, voted for someone else — a rare move in a closely contested race. [...] Hudson’s status as a ground zero of sorts for double haters was mirrored in the state as a whole: Biden beat Trump by less than 21,000 votes in Wisconsin, while nearly 57,000 voters cast ballots for someone else. [...] The Post-Schar School poll surveyed 3,513 registered voters in Arizona, Georgia, Michigan, Nevada, Pennsylvania and Wisconsin. These six states narrowly voted for Biden in 2020, but five of them backed Trump in 2016. The poll also focused on a group characterized as "Deciders" — voters with sporadic turnout or who are uncommitted to Trump or Biden.
