Opinion | Trump’s Best Strategy to Beat Harris Is Actually Pretty Simple

With the defenestration of Joe Biden and the ascent of Kamala Harris, conventional wisdom has gone from asking, “How can Donald Trump lose?” to, “How can he win?”

It’s basically a tossup race, but a successful Harris rollout and convention, coupled with a stumbling Trump performance since Mr. Biden’s exit, have created a sense of irresistible Harris momentum.

As usual when he falters, Mr. Trump is getting a lot of advice from his own side.

For as long as Mr. Trump has been in the ascendancy in the G.O.P., he will go off on some pointless tangent and Republicans will urge him — perhaps as they hustle down a corridor of the U.S. Capitol — to talk about the economy instead of his controversy du jour.

A close cousin of this perpetual advice is the admonition that Mr. Trump should concentrate more on the issues in this campaign. Neither recommendation is wrong, but they are insufficient to making the case against Kamala Harris.

Presidential races are won and lost on character as much as the issues, and often the issues are proxies for character. Not character in the sense of a candidate’s personal life, but the attributes that play into the question of whether someone is suited to the presidency — is he or she qualified, trustworthy and strong, and does he or she care about average Americans?

Presidential races, in this sense, are deeply personal; they usually involve disqualifying the opposing candidate, rather than convincing voters that his or her platform is wrongheaded.
