The senator because he represents the people
“The colonists called it the French and Indian War, and it permanently shifted the global balance of power. By the mid-18th century, both the British and French wanted to extend their North American colonies into the land west of the Appalachian Mountains, known then as the Ohio Territory.”
Well, when you think about this, everyone would yell, "NO TAXATION WITHOUT REPRESENTATION!!" Also, I am taking APUSH this year, so I would have to say that their greatest complaint would be the fact that the colonies had no representation in Britain's legislature; even though, the colonies were complaining about all of these. Don't quote me on this, but I hope this helps you!!
