538: Our Final Forecast For Arizona, Florida And Illinois Shows A Big Biden Lead [View all]

In an extraordinary move, Ohio postponed its primary election at the last minute due to concerns about COVID-19, meaning just three states will vote today — Arizona, Florida and Illinois, the latter two of which are among the 10 most delegate-rich contests in the Democratic presidential primary.

But despite the bumps in the road, the Democratic nomination race continues, which means it’s time for FiveThirtyEight to once again freeze its forecast to see what the outlook is in each state. (Remember, we won’t be adding any new polls, endorsements or other data to our forecast until we have results from tonight’s contests.)

Overall, the top-line outcomes in these three states are pretty straightforward: Former Vice President Joe Biden is the heavy favorite, with a greater than 99 percent chance of winning the most votes in each state, according to our forecast. On average, Biden is projected to win anywhere from 59 percent to 67 percent of the vote, which doesn’t leave Sen. Bernie Sanders with much of a shot in any of these states.

The main thing to watch tonight will be the margins between Biden and Sanders, as these will directly affect the delegate race. Blowout wins for Biden could also push the race toward its de facto conclusion and may even prompt Sanders to drop out. Although this scenario is unlikely, we shouldn’t completely write off an election surprise, especially considering we don’t know how the COVID-19 virus may affect these elections.
