Can someone explain what a delegate exactly is?
Palestine
A community for everything related to Palestine and the occupation currently underway by the occupying force known as Israel.
Anti-Zionism is not anti-Semitism. Existence is resistance for Palestinians.
Please refer to Israel as Occupied Palestine, or occupied territories. The IDF is a fascist and ethnonationalist occupying force. Israelis are settlers. We understand however that the imperial narrative (which tries to legitimise Israel) is internalised in the imperial core and slip-ups are naturally expected.
We always take the sides of Palestine and Palestinians and are unapologetic about it. Israel is an occupying power whose "defence force"'s (note the contradiction) sole purpose for existing is to push Palestinians out so they can resettle their rightful land. If you have anything positive to say about Israel we do not care.
There's a bunch of different categories so I'll keep it general.
A delegate is someone who votes at the national party convention on behalf of the people who voted in the state or district party primary election for a given presidential candidate.
It's basically the electoral college but for the party.
Yep, and they can even be faithless electors, as demonstrated in this convention.
Until 2018 the Democrats even allowed their "superdelegates" (typically elected officials from the state levels) to vote for whoever they wanted, no faithless action required. That could (and maybe did?) swing candidate selection, as superdelegates make up 15% of the total.
