Senator Henry Cabot Lodge.[34] Coolidge forged another key strategic alliance with Guy Currier, who had served in both state houses and had the social distinction, wealth, personal charm and broad circle of friends which Coolidge lacked, and which would have a lasting impact on his political career.[35] In 1907, he was elected to a second term, and in the 1908 session Coolidge was more outspoken, though not in a leadership position.[36]

Coolidge's home (1906−1930) in Northampton, Massachusetts
Instead of vying for another term in the State House, Coolidge returned home to his growing family and ran for mayor of Northampton when the incumbent Democrat retired. He was well liked in the town, and defeated his challenger by a vote of 1,597 to 1,409.[37] During his first term (1910 to 1911), he increased teachers' salaries and retired some of the city's debt while still managing to effect a slight tax decrease.[38] He was renominated in 1911, and defeated the same opponent by a slightly larger margin.
