Seriously: Franklin? International Superstar. Hancock? Richest man in the colonies. Washington and Jefferson? Plantation Owners from the Old Dominion. Amongst the leadership, the closest you get to what we would today call the middle class was John Adams, and that's a bit of a stretch.
And the People? Support for the Revolution ebbed and flowed with the fortunes of the Continental Army, whose members were largely those who couldn't find better paying jobs. At any point in time throughout the conflict, fully one-third of the population were Tories, one-third patriot and the rest vacillating with the fortunes of war.
But hey, if Obama can now re-write history about his "disavowal" of the middle class and "middleclassness" under the tutelage of Rev. Wright, then I suppose you can re-write anything.
