Kamala Harris and Donald Trump are veering sharply in how they gear up for Tuesday’s presidential debate, setting up a showdown that reflects not just two separate visions for the country but two politicians who approach big moments very differently.

The vice president is cloistered in a historic hotel in downtown Pittsburgh where she can focus on honing crisp two-minute answers, per the debate’s rules. She’s been working with aides since Thursday and chose a venue that allows the Democratic nominee the option of mingling with swing-state voters.

Trump, the Republican nominee, publicly dismisses the value of studying for the debate. The former president is choosing instead to fill his days with campaign-related events on the premise that he’ll know what he needs to do once he steps on the debate stage at the National Constitution Center in Philadelphia.

“You can go in with all the strategy you want but you have to sort of feel it out as the debate’s taking place,” he said during a town hall with Fox News host Sean Hannity.

Trump then quoted former boxing great Mike Tyson, who said, “Everybody has a plan until they get punched in the face.”
