A dojo is not democracy. Students can't elect a sensei - it must be a bad joke. This is biggest nonsense I've ever heard.
I think you are not in the right place - you have not capacity to be instructor nor the leader of the dojo.
Do you have any teacher? Is he aware you are teaching? Who taught you aikido?
Leading a dojo has nothing to do with Alpha, beta or whatever nonsense. It is a lot of responsibility and you must be able to deal with difficulties and not trying to find cheap excuse for your evident weakness.
A dojo is not a democracy, that is correct. But if this dojo has chosen to run itself in this manner (and from the tone of the original post, it has) then who are you to say differently, and what makes you think your post in any way helps?
The tone you are taking in this post sounds just like the student the original poster is having an issue with; arrogant & full of ego.
