What Went Down In The April 26 Primary Elections

Now that all of the states voting today have been called, I can report that FiveThirtyEight’s polls-plus and polls-only models got every state right on both sides. Interestingly, despite one of the largest upsets in polling history in Michigan, that state remains the only one that that the polls-only forecast incorrectly projected on the Democratic side. Iowa, Kansas, and Oklahoma were the only ones incorrectly forecasted by the polls-only model on the Republican side.
