I feel the need as the year winds down to share with you this video of Barack H. Obama eulogizing the late John S. McCain.

It’s about 19 minutes long. You need to set aside some time to watch it. I am gripped and saddened by the unspoken truth that the former president speaks about his former rival and how it reflects on the present day.

President Obama speaks at length about the differences he and Sen. McCain had between them. He speaks of when the two of them would meet in the Oval Office just to chat, “about policy . . . and about family.”

He tells us that even though the two of them held profoundly different world views that they both understood that “we are on the same team.”

I want to bring this to your attention yet again just to remind us all of what is missing in today’s discourse. The current president and many of our congressional leaders cannot seem to accept that they, too, are supposed to be on the same team. Have you heard Donald J. Trump say anything remotely like that? Or, for that matter, have you heard it from many of his foes on Capitol Hill?

The poison that has infected the current climate needs to be cleansed, wiped away. Will it disappear any time soon? Not likely.

I just hope there’s a residual sense of what Barack Obama recalled about John McCain left that it can someday be revived and returned.
