For many years, Strahan attended debates in Parliament and wrote reports of the proceedings that were widely circulated; his paragraphs of political news were frequently printed in the Pennsylvania Gazette, and he became a friend of its owner, Benjamin Franklin. His protégé, David Hall, succeeded Franklin at his print shop in Philadelphia when Franklin retired in 1747. At first he sympathised with the grievances of the American colonists, disapproving of the Stamp Act and publishing arguments in favour of a reconciliation in his London Chronicle. However, he later developed a much more hostile attitude, writing to Hume in 1775 "I am entirely for coercive methods with these obstinate madmen." In 1774, he purchased a seat as MP for the Wiltshire borough of Malmesbury, sitting as a supporter of Lord North'sTory administration. He represented that constituency until 1780, and then Wootton Bassett from 1780 to 1784, when he stood down because of ill health. He died the following year.
