The Joe Biden-Kamala Harris presidential ticket has made a pledge it might have difficulty keeping.

They have declared a “partisan cease-fire” while Donald Trump is mourning the death of his brother, Robert. It’s a grand gesture, showing a brand of empathy and compassion we complain has been lacking in the current president.

But how are Joe Biden and Kamala Harris going to avoid taking shots at Trump while their political party stages its virtual convention in Milwaukee beginning on Monday?

Presidential nominating conventions by definition are the most partisan events imaginable. Speakers usually spend their podium time trashing the folks in the other party. You know?

Well, let’s just see how this plays out.

Donald Trump certainly is entitled to an appropriate amount of time to mourn his brother’s death. However, politics awaits.
