God it's just like the Republican process last time lol
That's how Trump stayed out in front the whole time
There are two important differences: first, Trump was getting ~35%, while Bernie is polling at around ~25% nationally. For a factional candidate running against a fractured field, this makes a huge difference. And second, the GOP is using winner-takes-(almost)-all allocation in much more primaries than the Democratic party, which is using a very proportional allocation (among candidates above the viability threshold of 15%).
Due to the winner-takes-all nature of the early contests in 2016, Trump was able to very quickly run away with the delegate number. By the time the party establishment had realized that Trump was for real and that their preferred candidate JEB! was a complete and utter failure, it was basically already too late to rally around a single Trump-alternative. And then, the GOP establishment had to weigh the damage to the party inflicted by a Trump candidacy against the damage inflicted by stopping the front-runner who's got a majority of the delegates and the most passionate following at a highly contested and swampy convention.
Due to the more proportional allocation, the DNC in 2020 has much more time before Bernie approaches a delegate majority. If Bernie heads to the Democratic convention with say 35% of the delegates, they can still stop him.
