On April 23, a Superior Court in Essex County, New Jersey, ruled that no law forbids a member of a county Election Board from endorsing a candidate. Here is a link to the 4-page decision in Baraka v Adubato, 2170-14. The decision points out that in New Jersey, parties appoint members to county election boards, so there is no expectation that a board member will be politically neutral. Thanks to Rick Hasen for the link.
