The Ring sought out the most Powerful and fed upon the wearer's greed and ambition, always trying to get back to it's Master Sauron. The Elves were *incredibly* ambitious and a full of themselves *because* of all their might and power. The Ring always used that against them. In the book Gandalf said that even if the King were to hide the Ring in his deepest basement it would still work at his mind, trying to get him to use it. The Elves and the Mighty of M.E. knew that if they even *thought* about possessing the ring they would become like Sauron himself. Boromir is a case in point. The Hobbits were by nature not greedy or ambitious and therefore had a natural immunity to the Ring's influence. I hope this helps.
