Did I post too soon? A mayoral race that has been somnolent locally has now shown signs of life. The Ward 21 Democratic Committee has endorsed City Councilor Michael Ross for mayor. Ross currently represents District 8, comprised of Beacon Hill, Back Bay, Fenway and Mission Hill. A mayoral forum sponsored by a plethora of local groups (Allston Board of Trade, Brighton Board of Trade, Brighton Allston Improvement Association) will be held at WGBH this Tuesday night. Today, Representative Marty Walsh of Dorchester opened a campaign office in Oak Square. John Connolly, currently a city-wide councilor, is hosting a meet and greet this Thursday. And finally, a volunteer for City Councilor and mayoral aspirant Felix Arroyo, Jr. informs me she knocked on my door when I wasn’t home and left literature that I must have missed. So things are happening, but the general topic is still the heat of the summer rather than the political temperature.
