Just musing and I wonder if anyone else had this thought.
But I am wondering if there is an unspoken plan among established Democrats about pushing Joe Biden through as much as possible, just to have him then step down either before or after the campaign. It is no secret that the Joe Biden's mental stability may not fit the strain of a Presidential office, we've had numerous examples of it. If by half way through the campaign – say late Summer – Joe Biden's mental state may be a reason why he'd try to step down. What would the benefit of that be?
It would give the Democratic party a literal do-over, without the necessity of the voter-turn out – at all.
Vox amused the idea in 2016 when Trump and Hillary were already chosen by both parties as contendors.
"First things first: Clinton and Trump would have to personally choose to relinquish the nomination to lose it."
That means, there cannot be a forceful removal by the given party. Keep this in mind.
"But if a candidate did decide to voluntarily step aside, he or she wouldn’t be allowed to pick a replacement. Instead, either party would use a system a little like the Democratic Party’s superdelegates, but on steroids. The members of the parties’ national committees would get together to vote for whomever they want. The candidate with the majority of votes from the national party committees -- which consist of 350 people for the DNC and 150 people for the RNC -- would then become the presidential nominee."
"If either Trump or Clinton stepped aside, the parties’ chairs would have to call a meeting of the full body of the national committee. We’d then have something like a mini convention -- except without any of the pledged delegates that are chosen by the voters through the primary system, and, presumably, far more accusations that American democracy is run by a tiny, elite cabal."
The benefit of this is that the Democrats are almost united by the idea of doing whatever is necessary to get rid of Trump's Presidency. A sudden switch-a-roo like that would obviously stink up the election process, but if such a system can present a far better candidate that has a much better chance?
Right now there are two major contenders. Bernie Sanders, and Joe Biden.
If the Democratic Establishment did want to implement such a plan, it would be extremely difficult to force Sanders to do it, I don't think he would go a long with it, when he's in the position that he is in. Besides, I would say he's far more idealistic, and would use such an event to fire up his own passionate base.
Biden however has an easy way out if he needed it. Not only is it an easy out, it's honorable, if he acts more broken down and "lost" the more he can make the case that he is not fit to carry such a victory and wants to give the party a much better candidate.
And so what if this happens later on in the campaign. Say, after the early voting starts?
According to the above article: "It turns out the party’s new candidate would essentially get the votes cast for the previous one. This is because when voters head to the polls, they’re not really voting for a presidential candidate. Instead, they’re voting to select the representative that will represent their state at the Electoral College, which in turn meets in December to officially elect the next American president."
So if early voting predicts a Trump lead over Biden, this would be opportune window to make the switch.
This could also happen post election, if Biden is set to win. If that is the case I'd be very careful to see who he selects as his running mate.
