Combining brains and charisma is very rare in a politician. Obama being the textbook example - senior law school lecturer but also has the emotional depth and natural charm.
I’d think the list is shorter of charismatic politicians who hadn’t gone to a top notch law school. Plenty use brains and charm. Even spineless hacks like Mitch McConnel know how to be charismatic around wealthy republicans, and are brilliant, just brilliantly evil.
And he was accused of being a “secret Muslim” trying to bring Sharia law by a large percentage of the population.
That and trying to use the military to “takeover” Texas.
