What Went Down On Super Tuesday

Sarah, political scientists David Broockman and Josh Kalla had an interesting article last week delving into general election support of Sanders and Biden in hypothetical matchups against Trump. One of their key takeaways was that Biden and other more moderate Democrats picked up votes among Republicans, while Sanders had a group of younger supporters who didn’t plan to turn out if he wasn’t the nominee.

This from our friends at The Washington Post, who are also tracking tonight’s exit polls, is particularly striking — Biden is mopping up support across the board, except among younger voters and very liberal voters:

Is that a risk for Biden’s coalition in a general election situation?

Tennessee is actually the most uncertain state to have been called so far; Biden was “only” a 68 percent favorite there, per our forecast.
