I know I’m just a child and I’m not as wizened as everyone else scolding me, but let me break it down for you as clearly as I am capable of with my childlike brain.

There are three scenarios that are all about equally as likely at the moment.

1. Bernie wins 50 percent of the pledged delegates and is nominated.
2. Bernie wins a strong plurality of the pledged delegates and is nominated in a contested convention
3. Bernie wins the most delegates, but in the contested convention, it’s decided based on the fact that in head to heads Warren or Biden poll only a few points behind, that they nominate them as the ostensible “unity” candidate.

Now, I’ve stressed throughout that people are rational actors. They make decisions based on cost-benefit analysis, and I used my own experience only as an example. The folks who are going to be adjudicating this whole process are also rational actors. DNC Chair Tom Perez has stacked the rules committee against Bernie, which means that a contested convention is not going to be neutral.

One of the factors that these different groups will be weighing when they are making decisions that affect the outcome of this nomination process is how it will affect the race. If they feel confident that there is objectively no cost to №3, they will be more likely to do it.

It doesn’t matter what I personally do because I live in Washington State and my vote will have zero impact whatsoever on the outcome. But I’m telling you — this is not a threat, it’s a fact — if №3 happens, millions of Bernie Sanders supporters will sit out the race and Warren or Biden or Bloomberg or whoever will lose. You can wag your finger all you want, but this is the reality.

We have a rare opportunity where we don’t have to settle for the lesser evil. The candidate who has the best platform and the best chance at beating Trump is one and the same (by the way Sanders is almost in a statistical tie with Trump in my home state of Texas).

This isn’t a “purity test.” This is reality.

If you care that much about beating Trump, you will vote for Bernie Sanders to ensure he has more than 50 percent of the pledged delegates at the convention.

Any of the other scenarios will absolutely result in Trump winning.
