The vice president let Trump do the work of executing her strategy.

Vice President Kamala Harris did exactly what the political professionals said she should do.

In some cases, that was what operatives would tell any candidate to do in any election at any time: Don’t worry about the specific question you are asked, just use it as another opportunity to recite the lines we practiced.

In other cases, of course, Harris’ strategy in her first debate as a presidential nominee was custom-tailored for one specific moment and one specific opponent. She plainly used her long days of debate prep in a Pittsburgh hotel to compile a rich anthology of taunts, putdowns and derisive one-liners against former President Donald Trump. The rehearsal was enough to commit dozens of them to memory — not enough to avoid sometimes sounding a bit stagy in delivery. At times, one could almost see the candidate flipping through a stack of neatly organized 3-by-5 index cards in her mind.
