There is not a whole lot of daylight, at least on the surface, among the three candidates for East Hampton Village trustee whose names will be on Tuesday’s ballot. Rose Brown, Arthur Graham, and Bruce Siska are facing off, with the top two vote-getters winning seats. Mr. Graham and Mr. Siska are incumbents; Ms. Brown is taking her first shot at elected office. Narrowing the choice from three to two is difficult; all of the candidates are able and qualified.
