Career politicians, special interests and tons of money got comprehensively spanked in the Republic Primary process. Trump is an even worse choice - but he demonstrated that it is possible to beat the machine. Sanders came very close to doing exactly the same thing. The US system is significantly more favourable to insurgents than many.
It was interesting to see how the "establishment" Republicans tried at every turn to thwart and remove Trump from the process, but in the end relented (however much it pained them) because that's what the voters said they wanted.
The "establishment" Democrats were the same except they succeeded in placing their candidate ahead of what many believe their base really wanted.
