#11 – Barack Obama
Can you think of a man who has more on his shoulders than Barack Obama? The Democratic presidential nominee is busy campaigning against Mitt Romney in a very heated race. Oh, and he's also leading the most powerful country in the world at the same time. In an election year, and with a volatile Middle East and sluggish economy, the president's actions have never mattered more. The election will serve as his ultimate performance review, as voters will decide just how well he's been handling everything on his plate.
