Tuesday night President Donald Trump addressed Congress in a State of the Union-like speech. It was, by and large, a successful speech, one that added a few points to Trump’s low approval rating. Most notably, it sounded a positive note that was missing in his inauguration speech. It was “from the heart,” a call for unity, for working together to make America great.

Critics of the speech argue that, like Trump’s campaign speeches, was long on promises but short on specifics, especially on what will take the place of Obamacare. But Trump offered a design, if not a blueprint, for repealing the wreck that is Obamacare and replacing it with something better.

“We should help Americans purchase their own coverage, through the use of tax credits and expanded health savings accounts, but it must be the plan they want, not the plan forced on them by the government,” he said.

These kinds of speeches typically hit the high points and leave the details for later. The Affordable Care Act is a huge, complex system, and one can scarcely expect an in depth explanation of how it will be replaced in a one hour speech.

One thing we heard that we liked was near the end, when Trump called for unity and said “The time for trivial fights and small thinking is over.” We hope he is applying that to himself as well as to Democrats in Congress. Throughout his campaign and his first month in office, Trump has not been anything like the Trump who gave the speech to Congress on Tuesday. He has been insulting, combative, thin-skinned and vengeful. He has used his Twitter account as a weapon against his “enemies.”

One speech will not undo the reputation Trump has built for himself, but we shall see. If he can indeed moderate his tone and limit his Twitter activity, it will go a long way to creating an atmosphere in Washington that supports cooperation and unblock the logjam that has affected it for so long.
