Rosenberg predicts a tough ballot fight over legalizing pot

BOSTON – Senate President Stanley Rosenberg, a no-show at the launch of a campaign to defeat a proposed ballot measure to make marijuana retail sales legal, said Tuesday he still supports a third option that would make it more politically palatable for lawmakers to play a role in legalization if approved by voters.
Republican Gov. Charlie Baker, House Speaker Robert DeLeo and Boston Mayor Marty Walsh, both Democrats, teamed up last week to announce the formation of the the Campaign for a Safe and Healthy Massachusetts to fight legalizing pot sales to adults. Rosenberg, an Amherst Democrat, said that while he hasn't joined that group, that doesn't mean he supports the proposed ballot measure.
