Joseph R. Biden Jr. faces a potential “go” or “no go” conundrum next week and it has everything to do with the health of the individual he wants to defeat in the presidential election.

Donald Trump is infected with the COVID-19 virus, a potential fatal affliction. He checked into the hospital, then came out. Trump is not nearly “out of the woods,” as his doctors have said.

So here is the issue facing Biden: Does he participate in a joint appearance with Trump if the docs do not declare that Trump is virus-free? My own desire would be for the event to be postponed, or canceled if Trump is not cleared to go.

But this is a complicated matter that depends largely on the credibility of what we are being told by the administration.

Suppose the medical team tells Trump privately that he continues to be infected. Suppose, too, that Trump doesn’t reveal what the docs have said. Is the public supposed to presume that Trump is healthy enough to appear with Biden on a debate stage?

Are we supposed to believe a medical staff fully — which comprises military officers — if it does clear the president who by definition is the commander in chief and who has issued an order to tell us that the president is in the clear? Do these doctors adhere to the order given by the commander in chief?

The White House has zero credibility on these matters. I don’t believe anything that comes from Donald Trump’s mouth, or from any of the political hands who work directly for him.

If the president is still infectious, the session need not occur. Indeed, after witnessing the spectacle that unfolded in the first event, a repeat of that cluster fu** would do no good whatsoever.

Joe Biden says he wants no part of a joint appearance with an opponent who remains highly contagious. Who can blame him?
