He was a Sith Lord. It sounds odd, but I think the 3-year-old answer is just that good guys are Jedi, Bad guys are Sith.
I agree with the 3 year old answer, HOWEVER... The Jedi are an order, just like the Knights of Columbus, or the Freemasons, lol. I don't know if we have enough information about Palpatine's background story to know if he was ever a Jedi (i.e. if he ever joined the order). Since no one seems to suspect that he had force ability, I would guess that he did not join the order because surely someone would have remembered him, if this is true, then he is not a Jedi because he never joined the Jedi order.
