But you did say 2008, you said it was a "similar" result. I'm not going to contest the anomalous nature, but the result itself is not similar at all!
My point is that I don't agree, the numbers are only consistent for 2016/2020 (because turns out most people won't waste time with an uncommitted vote when there's a viable opposition candidate: Bernie). 2012 is a deviation and in the same way this primary did. The only thing different is the absolute number of votes altogether (in a state that has had insignificant population growth mind).
Hell, people don't want to admit it but he can end up losing Michigan too for taking up an anti-Israel stand. There's very clearly an "anti-protest" vote that kept uncommitted at only 10% of the vote despite getting 100k of them. About 400k voters that are at risk if Biden changes course.
