The American Revolution, from what I've always read, seemed to be very successful with transitioning the nation into independence. I became curious today though, and wondered if there were any prominent figures who later in life regretted the Revolution and independence.
Apparently early on Benjamin Franklin was hesitant about independence to say the least and somewhat pro-royalist views just before and during his time in London. He supported a number of unpopular policies including the Stamp Act of 1765 which didn't sit with colonists well. In fact his home was almost burnt down due to his political moves.
It was not until he returned to the colonies did he realise the full impact of the policies and have a change of view.
So yes there was some mixed sentiments amongst prominent figures in the revolution, though not after independence.
That said though if there was any remaining pro-royalist views, and there likely would have been amongst the general population, nationalism, public polices, and the culture at the time would have made it difficult for a person to express these views publically untill long after the war, if at all.
A politician stating a pro-royalist agenda could of potentially ended his carreer.
