As longtime readers know, I am a life-long Democrat. The part of the party to which I was attached was the oldest part, but it has largely ceased to exist in the current generation. It was Jefferson's part, in other words, and Jackson's; lately it was Sam Nunn's and Zell Miller's. Jim Webb (war hero Marine, former Senator, former Secretary of the Navy, former Assistant Secretary of Defense, diplomat, scholar, author) made a run at the nomination in 2016 and failed, to the sorrow of the nation whether it knows it or not. His departure from the field led us into the contest in which our options were Clinton and, well, you know the rest.
At this time the Democratic contest has narrowed to Joe Biden and Bernie Sanders, with the other candidates seeming to be also-rans. I could hardly agree less with Bernie Sanders on public policy or political philosophy. Nevertheless, he is the better man.
He is the better man because he is a man of his convictions; Biden, as far as I can tell, has no lasting ones. Bernie was arrested with the Civil Rights marchers in the 1960s, visited with the Soviets on his honeymoon, and has been a self-declared Socialist since the era when most Americans viewed that as a synonym for both "Communist" and "Satanist." Bernie really believes what he claims to believe.
You may not be impressed by his convictions insofar as you think that the convictions are bad, since it will reliably mean that he will attempt bad things. That is a strategic error. Even if you are unalterably opposed to his convictions, an enemy of conviction is to be preferred. A man of conviction can be predicted; on the principle of 'know thy enemy as thyself,' per Sun Tzu, he is the better choice of an opponent.
But also, he is the better man because he does not seem to despise anyone. Jim Webb and he became friends, and supported each other at the first debate in 2016. Bernie took fire in that debate and elsewhere for being willing to avoid gun control; he said, rightly, that coming from Vermont he had to respect the wishes of the rural population. That sentiment will serve him and the nation well should he happen to be elected.
Finally, he is the right man to lead the Democratic field in 2020 because he is the purest advocate for their animating vision. They need to know now whether or not that vision can in fact take root in America; we all need to know it. The answer to that question will determine a very great deal of future history.
For all of these reasons, then, I endorse Bernie Sanders in the Democratic primary.
