You know by now that my political prediction habit has been set aside because of poor past performance.

So, when I offer a possible scenario playing out I usually cover my posterior by saying that “I won’t be surprised” if such-and-such happens.

With all of that laid out there for you, I want to offer a brief look ahead at what I think could happen in the next bit of time as four more states conduct Democratic Party presidential primary elections on Tuesday.

Florida, Ohio, Illinois and Arizona Democrats are voting for their party’s presidential nominee. Two main candidates are still standing: former Vice President Joseph R. Biden Jr. and Sen. Bernie Sanders; a third pretender remains, U.S. Rep. Tulsi Gabbard. It’s down to Joe and Bernie.

What could happen Tuesday? Let’s try this: Biden scores huge victories in all four states and collects about 300 (give or take) more delegates to the national nominating convention. He builds a gigantic delegate lead over Sanders. He slams the door shut on Sanders’ path to the nomination and tosses the key into the drink. What does Sanders do?

In my mind, Bernie needs to then call a halt to his campaign. It was a valiant effort but there’s no way on God’s good Earth he gets the nomination. He concedes to his “good friend Joe,” and then endorses his candidacy, vowing to make good on what he said Sunday night at the debate he and Biden staged, that he will work to “defeat the most corrupt president in modern U.S. history,” Donald John Trump.

Biden and Sanders share a common goal, to boot Trump out of the Oval Office. If Sen. Sanders is a man of his word, and I believe that’s the case, then he will realize that with no path forward, any effort to continue is futile.

Does he extract some concessions from Biden? Sure. That’s what politics is all about. Dare I call it seeking a quid pro quo? Sanders could offer to leave the race and throw his support behind the victor, but only if the other guy, Biden, buys into some of the more progressive planks in his platform.

Will any of this happen? I certainly hope it does. I hope the party unifies behind the winner of the fight, gathers its wits about it and then goes straight after the man who never should have been elected to the presidency.
