The mainstream reviews of President Trump’s first State of the Union address Tuesday are begrudgingly glowing. NBC’s Savannah Guthrie said “it was optimistic; it was bright; it was conciliatory.” CNN’s Jake Tapper noted “the inspirational stories of Americans, and the calls to unity, and the beautiful prose.” Fox News’s John Roberts called it “very powerful—very patriotic.” White House aides may hope this praise will help reset the Trump presidency. But that won’t happen unless they and the president take action to fulfill Mr. Trump’s call for “the unity we need to deliver for the people we were elected to serve.” What follows the State of the Union address is more important than the speech itself. Mr. Trump called Tuesday for bipartisanship and united efforts to make America better. That should become a regular theme. He presented an agenda; now he must deliver it so voters will realize he has worked hard to meet his commitments.
