I am not worried about Bernie Sanders age.. if he decides to run

4. We need to all be sobered by the typically NARROW victory

margins both parties have had in this century.

Political scientists expect this to continue for some while, with power possibly thrown from one party to another in election after election in a very destabilizing and undermining manner.

Therefore I say: ANY candidate who runs a splinter or third-party campaign from the left in this environment IS, by definition and de facto, willing to accept continued Republican hold on power as an alternative to winning.

That wasn't a new reality in 2016, and it won't be in 2020. Third party input could be a plus back in the New Deal and early Reagan eras. It's a recipe for national destruction in this one.

Witness post 2016.
