Bran the Broken is the most dumb shit ever.
Bran is basically a pagan priest and has done nothing of any importance for anyone at the meeting, except the Starks.
He's not done anything useful in the series except arguably to reveal Littlefinger's treachery and warn Jon about the whitewalkers.
Let's see who's there:
Tyrion is supposed to be wracked with guilt and wants to protect the innocent, yet he eulogises for someone who did nothing to stop the massacre of the population. Why would he want Bran in charge?
Sam likes Bran, so there's one vote I guess
Davos hates magic and really hates people using prophesy and destiny to justify evil acts. Why would he want Bran in charge?
Yara, the Prince New of Dorne, Edmure, Lord Royce, Gendry, Sweetrobin and the two other random guys havenever heard of Bran before this meeting, except maybe as Ned Starks young son who should by rights be Lord of Winterfell instead of Sansa. What fucking story is he supposed to have that would resonate with these people? I bet the New Prince of Dorne must have a way better one, since somehow he went from not existing to rallying a kingdom behind him.
Brienne knows a bit about Bran and is a Stark loyalist, so that's another vote, but I don't see why a non-landed knight gets a vote...
Sansa knows all about Bran and is his sister, but she's the only one that doesn't vote for him!
Arya gets no vote but threatens to kill those who oppose one of her brothers and I guess they've all heard what she did to the Night King and the Freys. Hmmm, maybe I've discovered why everyone has a newfound love for Bran... bending the knee to King Bran is better than becoming the New Prince of Meat and Potato or the Lord Paramount of Steak and Kidney.
