President: Theodore Roosevelt
Teddy Roosevelt was, without a doubt, our most badass president. He delivered speeches while afflicted with open gunshot wounds; he led a group of soldiers known as the "Rough Riders;" and he hunted everything that moved. He was basically an American version of Saxton Hale.
While leading the Rough Riders he rode a horse by the name of "Little Texas," but during his presidency his favorite mount was a beast named "Bliestein."
