I still think Sanders will win. They might pressure him and corner him to force him to make concessions in the end if no one gets the required delegates, that's the most that will happen, but I think he will win. Warren might endorse him but again, he would have to make concessions. Thing is Biden cant win so Trump will .... and four more years of trump means the world and this time USA too is going to have the worst period in history. Yes the democratic party naturally wouldnt care, but American interest is on the line so the party will have to change. If they dont accept Bernie's gradual progressive change of their party then their party will collapse for good. Either way the Sanders movement can continue after the elections in another fresh party and a new overall political system but that would mean more radical change so does the dem party prefer that ? He's actually very moderate and not a radical, he's trying to take it slowly.
Also Tulsi is going to be a person to look at in the near future. The fact she is still in the race despite having no chances means she is trying to prove or even create something on the political scene.
All in all, America has to change. If Bernie isnt elected now and the change happens more peacefully, there will be much more violent change after Trump gets elected again.
Not really. If you'd assume that DNC understands that neither of their candidates has a prayer against Trump, then DNC'd rather have Joe's to lose to Trump (even if with embarrasment) than see socialist and by association Democrat Party being destroyed during General Elections.
