In an intriguing outcome to yesterday’s East Hampton School Board vote, residents opted for three newcomers, saying no thank you to one incumbent who has strong ties to the community. This may well signal a level of anger with the district over its poorly handled, surprise demotion of Gina Kraus, the popular John M. Marshall Elementary School principal, as well as a long period this year when the East Hampton Middle School principal was absent for what was described as a medical problem.
