Highest Office Held: Kansas Senator
Most failed presidential candidates take a step out of the limelight after a loss, as it's a great time to lick the wounds. Case in point: We haven't heard much from Mitt Romney lately.
Bob Dole took the opposite tack by becoming a pitchman for Viagra. The boner gig led to other spots for Visa, Dunkin' Donuts, and Pepsi. In case you forgot, or somehow missed it, please watch this long-ass commercial wherein Bob Dole creeps on Britney Spears, dirty old man style.
