Just wondering: When have you ever heard someone describe the president of the United States as an “existential threat” to the very nation he was elected govern?

Never? Maybe once in an epochal age? Yeah, maybe.

Former Vice President Joe Biden, one of many Democrats seeking to succeed Donald Trump as president, has called Trump such a threat to the nation.

He is touring Iowa, that key caucus state that kicks off the presidential campaign. He is talking about Trump’s politics of fear and division; he is warning us about Trump’s attacks on American institutions, such as the media.

He is going straight after Donald Trump’s character, or lack of character. He is calling the president a criminal and someone who cannot be trusted to represent this nation firmly on the world stage.

Yes, that is how I would describe the president as well.

Those elements comprise an existential threat to the very nation that somehow, against all reason and odds, elected him to the most noble office in the land.

Still, the hear such a description coming from a major candidate for that office call the incumbent an “existential threat” takes this discussion to a level I do not recognize.

It’s only going to get stranger.
