It’s hard to sum up tonight when we still don’t know who will win half the states, although I guess we know that Biden will pad his delegate lead a bit. But I can sum up the Democratic primary race: Biden will be the nominee, although I would have said the same thing before tonight too. Basically, what tonight did was confirm that Biden is leading in the states we think he is leading in. His win in Michigan tonight was especially good for him, as it confirmed that there wasn’t some hidden reservoir of Sanders support in the industrial Midwest. In short, tonight’s results were consistent with a national Biden lead of ~20 points, and that is game over.
