We have observed that Joe Biden in office has made prior weak presidents (Carter, Obama) look better by comparison. It's good for Republican electoral chances but bad for our nation and the free world.
It should therefore be no surprise that Kamala Harris, likewise, has managed to make weak former Veeps (Biden, Quayle, Agnew) look better in the rear view mirror. The value she brings? Her shocking inability to successfully accomplish public presentations and manage a staff is probably all that stands between Joe Biden and the 25th amendment.
Afterthought: You’d be tempted to give the Biden team credit for intentionally selecting as Veep someone so demonstrably inept politically, as a way to protect the “big guy.” Mounting evidence seems to suggest they lack that much foresight.
I fear Harris is what she seemed on first blush, a box-checking affirmative action hire. History shows being hired for “who you are” rather than “what you can do” often results in nonperformance. In show business terms, such hires are props, set dressing.
