This kid's revolting & disgusting behavior may be no more than picking his nose and eating the contents, something that is fairly common among young children, or something much worse, such as taking toys and hitting children without any warning.
In any case, there is a process to be followed, and having a child voted out of the classroom is not part of that process. The classroom is seldom a democracy. Usually, it is, at best, a benevolent despotism, and kindergarten may be a good place to start teaching democracy, but not by voting a child out because others don't like him. Among other things, they may not like him because he has darker or lighter skin than they do, straight or kinky hair, or speak in a different language or dialect.
Maybe he doesn't have it, whatever it is.
Maybe he's just a little ass who need his butt whipped.
