Cynthia Houston, 84, had a flash of grumpiness when she went to vote yesterday in Boscawen: Her husband reminded her that she was supposed to bring a photo ID after they’d already gotten in line in the basement of the Congregational church. “He didn’t remember to tell me when we got out of the car,” Houston said. She had already started to leave when a town official stopped her and said she could still vote yesterday, which election officials considered a test-run for the implementation of the state’s new voter ID law. She wasn’t the only one to run into some trouble yesterday, the final election day in which voters could simply show up at the polls, announce themselves and receive a ballot. Yesterday, officials also asked for a photo ID, and voters who couldn’t or wouldn’t produce one were supposed to received a sheet informing them that on Nov. 6, they would need to produce a photo ID or sign an affidavit swearing they were who they said they were.
