Biden is bought and paid for by Big Business. If he doesn't perform, he can be taken out by a shooter or by one of many other ways. Joe and Hunter both know this. Maybe that's why Joe is losing his mind, and why Hunter is doing drugs. Escape mechanisms. They know they are dead any moment big Business wants.
If we talk about the influence of Big businesses over the American Politics and politicians, then you should not ignore the fact there are also Republican CEOs and big business owners which are major donators to the campaign of GOP representatives. It is a known fact there is a lot of money donated to both sides.
So what was the coping mechanism of Trump, Bush, or Clinton while there were in the White House, because they were also at mercy of the same big powers.
I would say that Trump liked to play golf and drink diet coke to forget about it as well.
Who knows for sure but, Trump actually has thought things through, Bush's daughter bought 10,000 acres of land in Argentina for him if he needs it, and Clinton has all those sexual escapades.
Biden knows that his opponents know how his people stole the election for him, and how he isn't really the real president. He Also knows that he needs to do the impossible for his own people considering the way they all have pulled his strings so far.
So, Biden is an enemy of three things:
1. His own people who he is failing;
2. The opposition who know that he is corrupt to the core;
3. His own, simple, fear... which might be more than the other two combined.
That's enough to drive anybody nuts. If they are going to do it... it's the waiting and wondering.
