If there was a unifying theme to President Trump’s campaign, it was his pledge to serve America’s “forgotten men and women,” working people forsaken by the economy and Washington.

In his speech Tuesday night to a joint session of Congress, Mr. Trump presented himself as having made an aggressive start at championing the cause of working people, and promised a new era of rising wages, bustling factories and coal mines, sparkling air and water, and cheaper and better health care, all behind a “great great wall.” He told a few whoppers, but largely kept his eyes riveted to his teleprompter and his delivery subdued. He even opened his speech with a long-overdue condemnation of hate “in all of its very ugly forms.”

We heard again the same sorts of gauzy promises and assertions of a future Edenic America, a sort of Trumptopia, that characterized his campaign. He didn’t explain how he would get it all done, much less pay for any of it; indeed, it sounded at times as though he were still running for the job, rather than confronted with actually doing it. Across his first few weeks in office, Mr. Trump has shown little sign of delivering anything for working Americans beyond whatever satisfaction they may derive from watching him bait the Washington establishment and attack the reality-based media.

Mr. Trump likes to describe his chaotic first month as “promises kept.” Really? Remember how he promised during the campaign to “immediately” fix Obamacare and deliver “great health care for a fraction of the price”? He hasn’t even put a plan on the table. On Monday, he complained to the nation’s governors that “nobody knew” replacing Obamacare “could be so complicated.”
