April 12th – Hillary Clinton launches campaign
Hillary Clinton officially launches her much-anticipated bid for the presidency with a sleek rollout video and a road trip to Iowa in her "Scooby Doo" van.
“Americans have come back from some pretty tough economic times. Our economy and our country are much better off because American families have basically done whatever it took to make it work. But I think it’s fair to say that as you look across the country, the deck is still stacked in favour of those already at the top. And there’s something wrong with that.”

August 6th – first Republican debate – Megyn Kelly gets tough with Trump
Sixteen Republicans. Two debates. What could go wrong? The 10 candidates fought it out at the Fox debate, but Trump stole the show. He lost his temper over Megyn Kelly's grilling over his misogynistic commentary. He also proposed a wall with a "beautiful door" and refused to rule out a third-party bid if he didn't win the nomination.
"Mr Trump, one of the things people love about you is you speak your mind and you don't use a politician's filter. However, that is not without its downsides, in particular, when it comes to women. You've called women you don't like 'fat pigs', 'dogs', 'slobs' and 'disgusting animals'.
In a later interview, Trump insinuates Kelly's tough line of questioning was because she had "blood coming out of her wherever".
