I remember an episode of the lawyer series “The Practice” about something similar — where the client calls his lawyer because he’s been pulled over for DUI and the lawyer tells him to step out of the car and start drinking in view of everyone.

No, I’m acting like it’s a close race and Kamala doesn’t need to gamble on another debate. It’s not about her “winning”. Trump’s base doesn’t care how he performs at a debate or what he says at a debate — they are going to vote for him no matter what. Kamala’s base does. She’d just be opening herself up to performance criticism and other press “gotchas” at this point. There’s just no need and it would accomplish nothing.
