The fact that we have to see and hear Donald Trump every day for the next 8 years.
But the second worst part?
It was being left out of the conversation by the Democratic Party, who ignored the candidate people wanted, in order to back someone that would be easier to control. A person they knew people hated.
But the third worst part?
Finding out that there are way more monsters in the United States than I once thought. And now they have all of the power for the next few decades(remember: Donald gets to pick the replacement for Scalia on the Supreme Court. That shit is going to haunt you for the rest of your natural lives, at the very least).
But the fourth worst part?
It was totally preventable. And no, I don't mean in any kind of fantasy about assassinations, I'm talking within the systems we were given. They had all of the time in the world to prepare for this. They had the whole world, and Donald himself displaying exactly why they should not have let him win. They had everything they needed to win fair and square, and they fucked everything up.
The system did not fail. The people did. The people failed to understand the most important part of a presidential election in the U.S.
