It all seemed clear after that Harris-Biden moment in Miami. Today, things look muddier.

In the moment and in the hours after, it was must-see TV: a clash between a rising black female senator and a former vice president. Kamala D. Harris won the Democratic debate encounter with Joe Biden and left Miami on a wave of positive reviews. But today, things look a little more complicated.

What happened that Thursday night in Miami is an example of how politics operates today. As President Trump has shown again and again, performance and showmanship matter. Every moment can become magnified, but only a few things stick for very long, especially when the questioning starts. Was the Democratic nomination battle fundamentally changed by the first debate? We’ll see. CONT.
