Pulls to right and outside of right tire wearing on 1999 Mercury Villager

I have a 1999 Mercury Villager which pulls to the right while driving. The steering wheel turns slightly to the right the entire time I am driving. The right front tire is wearing quicly on the outside. Car was aligned twice, but still pulls. Tires on front are new. Need help to understand what may be the cause.
