First things first, there is no practically 0 chance that any Dem candidate who isn't Bernie will get a plurality. Bernie is doing well enough that he is practically guaranteed to attain at least a plurality of delegates, if not a majority.

I've narrowed it down to three outcomes barring any Black Swan scenarios.

1. Bernie Sanders wins a majority of delegates
2. Bernie Sanders wins a plurality of delegates, then becomes the nominee anyway after a contested convention
3. Bernie Sanders win a plurality of delegates, then gets denied the nomination at the convention.

In the 3rd scenario, Trump is practically guaranteed a victory so we won't have to really worry. In the first two scenarios, it's Bernie vs Trump, and I think there's a legitimate chance that Bernie wins, even though it's moreso a measly ~20% chance.

Ergo the only scenarios where we have a race on our hands involves Bernie as the opponent, so it's time to kick the war against "democratic" socialism into overdrive.

Are you ready to campaign against "Democratic" socialism for the next eight months?

Get ready to give retorts to all the most common talking points

"b-but if we just cut down on military spending we can give everyone quality health care and a quality education"

"b-but the republicans just support socialism for the rich!"

"b-but it's more like DENMARK AND NORWAY AND SWEDEN, not the Soviet Union"

"b-but medicare4all will actually lead to us paying LESS"

"b-but Bernie is authentic and consistent and genuinely cares!"

and all the others I haven't mentioned.

DON'T BE COMPLACENT. It's likely that Bernie loses to Trump but DON'T TAKE THAT FOR GRANTED! Be ready to persuade people on the fence - and there will be people on the fence who can be tricked into voting Bernie - that Trump is the way to go
