Hillary Clinton vs. Barack Obama
The 2008 Democratic Presidential race between Clinton and Obama got seriously nasty at times, and it ended up being a very close call. But didn't you ever think to yourself during all the campaigning, "why can't you guys just get along — you're BOTH huge nerds"? Clinton has been an intellectual powerhouse for decades, and Obama could have been a literary star if he wanted, but decided to nerd out on community politics, hip hop, and basketball instead. But as Abe Lincoln wisely said, "The best way to destroy an enemy is to make him a friend." Those two clearly took the words of the legendary president — and fellow uber-nerd — to heart by channeling their rivalry into an amazing professional relationship that has changed the world.
