Elections in the Queen City have been plagued by several glitches of late, but city officials are hoping for smoother sailing this Town Meeting Day. In October, the clerk/treasurer’s office, which is charged with overseeing the city’s elections, temporarily stopped early voting after accidentally leaving five of 15 Republican candidates for justice of the peace off the ballot. It had to reprint ballots — a $10,000 mistake. Then, roughly two weeks before the election, the office discovered that 87 voters in a New North End housing development had been listed in the wrong district. In 2012, the office misprinted a tax rate on ballots. There have been other snafus, too. The upcoming election on March 3 is a big one — due to redistricting, all the city councilors and school commissioners, in addition to the mayor, are up for reelection. After the ballot misprints, Mayor Miro Weinberger declared, “These avoidable and costly errors must end,” and he asked his chief administrative officer, Bob Rusten, to draft a plan to make that happen. Rusten presented it to the city council on Tuesday.
