Washington • The biggest impact of this week’s two-night, 20-candidate Democratic extravaganza is that a new star has emerged: Sen. Kamala Harris of California turned in one of the best debate performances I’ve ever seen. She earned herself a place in the upper tier of the crowded field. Now we’ll see if she has what it takes to climb all the way to the top — and stay there.
Harris’ ascent came at the expense of front-runner Joe Biden, who had such a disappointing outing that all he can do is make sure he does better next time.
