123. Answering your question...

Yes, an organization can be governed by certain principles, without every member of the organization agreeing to every one of those principles. If you must have an example... Susan Collins is a Republican, the party platform is pro-life, she's pro-choice. But it's kind of self evident. Do you really think that EVERY member of the Dem and Republican parties supports EVERY plank in their platforms? If anything, Sanders probably agrees with the Dem platform more than most Dems, because unlike most, he had the power to actually influence it.

re: "{Sanders} remains free to commit to it or not, or committing to portions thereof, or opposing it entirely, whatever suits him best at the moment."
Technically, every Dem has that same freedom. Nobody gets evicted from the party, even if their votes don't always tow the party line.

Meanwhile, I'd say Sanders has supported "proper" Dem positions to a greater extent than some "DINOs" have.
