Disinterested means to be impartial and not having any bias. Uninterested means a lack of concern with any specific topic. So a disinterested person can vote in an election but not care who wins. An uninterested person could vote but may not since they couldn't care less about the election in the first place.

Disinterested and uninterested are different.
