Representatives in the Massachusetts delegation were members of the American Party, including Speaker of the House Nathaniel P. Banks.

According to his New York Times obituary, Trafton "had been an active leader in the anti-slavery reform, and while a member of Congress he secured the cordial hate of his opponents by his bold assaults upon the slave power".
