In his astute and often clever way, Franklin dodged the internal-external issue, knowing full well most house members would not accept the idea of complete colonial autonomy on tax matters, while the colonists would accept nothing less. He hoped repeal would remove the immediate difficulty and parliament would avoid the taxation issue in the future.
The first might be the prerogative of the colonial assembly, the other of parliament. Undoubtedly, many seized upon the distinction between "internal-external" as a principle they could accept in the midst of a serious setback and failure. If so, they were helped along by a magnificent presentation by Benjamin Franklin, agent for Pennsylvania, who presented the colonial case to the commons.
