In 1906, the local Republican committee nominated Coolidge for election to the Massachusetts House of Representatives. He won a close victory over the incumbent Democrat, and reported to Boston for the 1907 session of the Massachusetts General Court. In his freshman term, Coolidge served on minor committees and, although he usually voted with the party, was known as a Progressive Republican, voting in favor of such measures as women's suffrage and the direct election of Senators. While in Boston, Coolidge became an ally, and then a liegeman, of then U.S. Senator Winthrop Murray Crane who controlled the western faction of the Massachusetts Republican Party; Crane's party rival in the east of the commonwealth was U.S. Senator Henry Cabot Lodge. 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. In 1907, he was elected to a second term, and in the 1908 session Coolidge was more outspoken, though not in a leadership position.
