Donald Trump’s approval rating is rising. The Democratic advantage on survey questions about party preference for control of Congress is vanishing. Liberal anxiety about the fate of the midterms — and I would venture, the country itself — is rising.

To all this, I say: Calm down.

Not relax. Not rest easy. Not coast. But stay the course and don’t panic. Work hard, message well and bring your passion — and a few neighbors and friends — to the polls in November.

If voters do that, as they have already done in special elections, signs are positive for a major realignment in Washington.

As a CNN analysis last month said: “These results suggest that the Republican Party is in trouble heading into the midterm elections. If past trends hold, it is possible Democrats could see a double- digit swing in the average House district in 2018 compared with past elections.”
