I'll snatch a snippet from what Rocketboy wrote in his blog, because it nicely encapsulates, why this will not work out for Biden, but will help Trump:BridgeConsoleMasher wrote: ↑Wed Apr 08, 2020 8:55 pmIn the case that newer Democrats implode the general? Sure. Biden will undoubtedly capture any drop of conservative Democrat uncertainty though.
You are not going to get the vast majority of Sanders-Voters to vote for Biden, if you discourage them from voting in the first place, precisely because of Sanders dropping out. You know what got Trump truely into his current position? The complete dissatisfaction with the political system, which gives voters the option to vote between two slightly different shades of brown. Trump is a FUCK YOU to the political system, so the cue for the democrats to win is, to shake the system to it's core, not to put more cement into their own shoes.Even if Bernie does not get 1 vote more, you should still want the process to run its course completely. It builds engagement, calling on people to do their part, and have their voice heard. Even if Bernie does not win, him winning delegates illuminates how different demographics feel and signals to Democrats what they should prioritize in the future.
Now, don't get me wrong. I don't think Sanders is the Holy Grail or am particularly fond of him as a potential president, but if your primary problem is the lukewarm reception of your candidate and a lukewarm voter-turnout, then you need to set fire to your voter-base, not douse it in the same stale water that the party has been treading in the last decade(s). Change! got Obama into office, not "Eh, let's not be too hasty and let's take two steps back before we, maybe, make half a step forward".
