I honestly didn’t even know there was a voter ID thing on the ballot until after the election. But saw a lot of press about how much money both sides, including Musk, were spending on the race. As well as several comments from Musk about how important the race was, and several comments from anti-Musk people about how “the Wisconsin Supreme Court race is a referendum on Elon Musk!”
If Musk really thought the voter ID thing was more important, he did a piss poor job of getting that message across.
Or, he moved the goalposts.
