In more than seven dozen interviews conducted in Wisconsin in early September, from the suburbs around Milwaukee to the scarred streets of Kenosha in the aftermath of the Jacob Blake shooting, about 1 in 5 voters volunteered ideas that veered into the realm of conspiracy theory, ranging from QAnon to the notion that COVID-19 is a hoax. Two women in Ozaukee County calmly informed me that an evil cabal operates tunnels under the U.S. in order to rape and torture children and drink their blood. A Joe Biden supporter near a Kenosha church told me votes don’t matter, because “the elites” will decide the outcome of the election anyway. A woman on a Kenosha street corner explained that Democrats were planning to bring in U.N. troops before the election to prevent a Trump win.
