Small, but interesting mention there that the Mount Rushmore equivalent is Whitestone Mountain which, if it's the same one, is in North Carolina.
There's a few conflicting things there, like Jackson dying in what seems to be a fistfight but getting the Lincoln/JFK martyred hero treatment. Van Buren struggling from the outset against the other branches of government and the Whigs but being re-elected in 1836 and 1840.
Some interesting ideas, but feel there's a lot of the why I'm missing.
