The intensity of the hyper-partisanship and profound division we currently inhabit becomes most apparent to me whenever I comment on what I regard as the occasional unforced errors of President Donald J. Trump. Any balanced commentator has experienced the bizarre sensation of being aggressively strafed from both sides simultaneously—for insufficient criticism on the one hand, or insufficient loyalty on the other. Yet one must call it as one sees it. As someone who has known Donald Trump personally for three decades, and as a presidential historian whose works on two American presidents stand as the official biographies recommended by their respective presidential libraries, my assessment is that while President Trump, like all of us, is not without flaws, he is a good man, and in my considered judgment he has, on balance, been a good president. Everyone is entitled to an opinion and can agree or disagree. But let me propose this litmus test: if you cannot list at least five of Trump’s major accomplishments or five of his failures, you are almost certainly inhabiting one of the two prevailing echo chambers. And my recommendation as an unlicensed psychologist is to switch off your computer or smart phone, draw a few deep breaths, step outside for a walk if the weather is nice, embrace your children or spouse if you are lucky enough to have them nearby, and remember that life is short.
