Of course he knows what the results will be. He owns twitter. He has all the admin passwords to the server that runs the poll. The admins that run the server answer to him. The result of this poll will be whatever Elon Musk wants it to be.

Yes = he gets to step away from the dumpster fire without it looking like it was his decision
No = all of his previous decisions are justified
Email to the admins: "Hey guys I'd like the results of the poll to be the following..."
No chance.
Interesting side note: Here in Australia this morning on the ABC public broadcaster's national News channel, one of the presenters said "if you hate Elon Musk, vote yes"... encouraging the mostly left-leaning ABC viewers to log on and vote Musk out. The poll will get swamped by this politically divisive Musk-hating recruitment drive, which is why the results stand as they are.
