I don't really think it's nesessary, if he's the leader it's his party, I don't think you have the right to take it from him.
Also, other players beside the leader may "suck" as well, so what do you do then? Take lead position from a perfectly fine leader just to kick that person?

How about trying to get along with each other in a friendly way?
Helping others improve and also listen to their ideas too? Because, you know, YOUR playstyle doesn't have to be the best.
And if you feel you have such a short temper you can't do it it's only fair YOU have the inconvenience of rebuilding the party. That leader had to gather 8 players, you only need one.
