Whilst hugely disappointing, I am not in the slightest bit surprised by this result.
Clintons campaign was doomed from the start. It's nothing imo to do with her being a women. And everything to do with an ineffective marketing campaign.
Firstly, know your audience. Clinton was out of touch with a vast majority of Americans and what they wanted. Trump knew who they were, knew what their issues were with life and how to appeal to this. Not all of them were gun-toting, white supremists. Many were ordinary people who felt Clinton and the Democrats just weren't cutting it and they didn't have an alternative.
Secondly, have a compelling message. 'Make America Great Again'.
Forget who's mouth it's coming from, this is inspirational, positive and strong.
'Stronger Together'. Meh. Not particularly original, and a hardly indicative of progression or change.
Thirdly, innovate. Offer a solution to your markets needs that's better than what's currently available.
People wanted change. Above all else, they wanted a better solution to what they had. They didn't want another presidential dynasty or more rising taxes and insurances and more democrats. They wanted change. Whilst a lot of us outside the US think Obama is great, a lot of Americans don't. They think he's weak and they want a strong leader.
Sadly HC just wasn't the right person to pull off another democratic presidency. They could've done, but the message and they way it was delivered didn't appeal enough to the people who ultimately could've changed the game.
