Newly elected State Senator Mike McGuire swept through San Rafael on Thursday, giving state-level answers to a few West-Marin questions along the way: He reaffirmed his commitment to affordable housing, offered ideas for how to best serve a growing population of senior citizens and signaled his support for legislation that would end personal belief exemptions for vaccinations. The 2nd District senator and third-generation Healdsburg resident spoke before a crowd of about 100 at San Rafael’s City Hall during a town hall meeting he hosted to discuss a wide range of issues, including climate change, park funding, fracking and foster care.

Mr. McGuire fielded questions while battling a cough, his energetic style often punctuated by shouts of “Hot dang!” On the topic of affordable housing, he called on the state to create more resources for redevelopment. “There are very few resources out there for affordable housing,” said Mr. McGuire, who serves on the senate’s Transportation and Housing Committee. “And we have to help people live where they work.” He also believes that one person ought to be in charge of overseeing the various state and county senior service departments, and that an overhaul of senior-service websites is needed. “It should be all on one portal, a one-stop shop,” he said. Responding to Marin’s measles scare, Mr. McGuire threw in his support proposed legislation written by Senator Richard Pan that would end vaccination exemptions. “I understand that folks want to have a choice,” he said. “That there is serious concern about it. But what these exemptions have done is allowed a disease that we thought was essentially extinct to be able to come back, with a vengeance.” Mr. McGuire also announced a plan to fortify telecom accountability and said he supports sea-level rise preparedness and reforms to the state’s foster care system.
