With not quite six weeks left before Newton residents vote on a requested $11.4 million in tax increases for schools, streets, and public safety, supporters and opponents are mobilizing across the city.

Signs backing the three Proposition 2½ override questions have cropped up in front yards, and supporters have held meetings with community groups and parent-teacher organizations. Opponents, meanwhile, have approached residents at coffee shops and appeared on a local television program to warn about higher taxes.
