Stop Donkys From Playing Trash

Hi All

I want to figure out a way to stop donkys from calling trash pre flop in a tournament. I am thinking I need to raise bigger. I am also thinking I need to just limp and call his raise try to catch a monster and take his chips. I would like to get some thoughts on the subject. What you think is a sound strategy for dealing with loose callers pre flop. Some other thoughts on the subject.

Posistion I think is key to playing aginst this player.
