Readers of this blog no doubt understand that I want Donald Trump to be defeated for re-election in 2020. He is unfit for office. He is unfit for public service at any level. I want him to disappear from public view. The sooner the better.

That all stated — yet again! — I am chagrined that one of the possible challengers to the president has decided to re-enter the fight.

U.S. Sen. Bernie Sanders, the independent from Vermont, is now a member of the gigantic and still growing field of Democrats running for president in 2020.

Please, Bernie. Why are you back in this race?

Sanders isn’t even a Democrat. He runs for the Senate as an independent, meaning he is unaffiliated with either major political party. He caucuses with Senate Democrats, votes with them on virtually all legislative matters and so I guess that makes him a  de facto Democrat.

My hope remains as I stated it some months ago: I want the next Democratic Party presidential nominee to be someone no one has heard of. I want that person to emerge from the tall grass, to burst on the scene with flair and panache.

Please forgive me if I sound like an ageist, but I also want that nominee to be someone a lot younger than the 77-year-old Bernie Sanders.

Bernie Sanders is a political retread. He ran for the Democratic nomination in 2016 essentially on a single issue: income inequality. He beat that issue bloody while losing the nomination fight to Hillary Rodham Clinton. It is a totally legitimate issue, but it is not the singular issue that commends him to the highest office in the United States.

Indeed, the senator needed to demonstrate a much wider range of knowledge than he has exhibited.

I suppose his candidacy elevates him immediately to the top tier of potential Democratic nominees. He’s up there with, say, Sens. Cory Booker, Kamala Harris, Amy Klobuchar and perhaps even Elizabeth Warren.

The roster of candidates is sure to grow. Goodness, it might exceed 25 or so candidates.

I want one of those Democrats to emerge as The One, the individual who can take the fight directly to Donald Trump.

It’s just not Bernie Sanders.
