California went nuts with the Democrat ballot harvesting, and Backstabber of the House "Eddie Munster" Ryan even remarked on it - but did nothing, because it was all part of the Uniparty plan against MAGA and President Trump.
Michigan actually went farther than most states, stealing 2018, and laying the groundwork for effortless Steals in 2020 and 2022.
