There has been rising anxiety among Democrats in recent weeks — and rising optimism among Republicans — about the midterm elections in November. Last night’s primaries in several states should cause everyone to take a deep breath. The Democrats had a good night:

Elliott Morris of The Economist said on Twitter, “but those numbers should make Democrats feel good about November.”

Democratic turnout was also strong in Iowa. And as analysts dig into the California results today, I’ll be watching for what they find out about turnout. Nate Cohn of The Times has a good explainer of California’s importance here.
