Boston Globe 6/24/10: Backers say sales tax cut to be on ballot. Voters in November will get the chance to slash the state sales tax from 6.25 percent to 3 percent, according to advocates who say they submitted more than enough petition signatures yesterday to force the item onto the ballot. Carla Howell — chairwoman of the Alliance to Roll Back Taxes, based in Wayland — said her group submitted about 19,000 signatures to town and city clerks by yesterday’s deadline, a comfortable margin over the required 11,099 signatures. Her group put similar measures on the ballot in 2002 and 2008, but neither passed.
