They gave you no opportunity to choose a successor but as I understand it, that was because the Democrats held the seat?
There is no requirement that an incumbent president must be the nominee. Centrist pro-genocide-and-nothing-else democrats sued to make sure no challenger to biden was on the ballot in all 50 states. Then biden stepped down and appointed harris. At no point were the voters asked. Anyone who voted uncommitted in the primaries was screamed at for being a traitor by people who demand affirmative support for genocide and nothing else.
People like you.
