5. Hillary Clinton, because she got Trumped.
Here's some major bad news for Clinton/America: for the first time, Donald Trump is leading in the polls. According to CNN, the silken-haired bankruptcy maven currently leads nationally with 44% to Clinton's 39%. (Third-party candidates Gary Johnson and Jill Stein held 9% and 3%, respectively.)
Pollsters attribute Trump's rise to positive feedback from the RNC (even though it was a mess) and fallout from the newly-leaked DNC emails, revealing a conspiracy to make sure Clinton defeated Bernie Sanders in the primary. All in all, Clinton is heading into her convention with some serious work to do, while all Trump has to do is keep saying racist stuff till November.
