#1 Most BadAss President.. Theodore Roosevelt
Checking Teddy Roosevelt's resume is like reading a How-To guide on ass-kicking manliness. He was a cattle rancher, a deputy sheriff, an explorer, a police commissioner, the assistant Secretary of the Navy, the governor of New York, and a war hero.
Out of all of his jobs, hobbies and passions, Roosevelt always had a special spot in his heart for unadulterated violence. In 1898, Roosevelt formed the first U.S. Volunteer Cavalry Regiment, known as the Rough Riders. Most people already know of the Rough Riders and their historic charge up San Juan Hill, but few know that, since their horses had to be left behind, the Riders made this charge entirely on foot. You just could not stop this man from violencing the hell out of a San Juan Hill.
