Tin Foil Hat Time once again!
Okay. You know how Trump always uses his FEAR-O-METER to point him in a political direction?
What does he fear the most, based upon his behavior?
I think that answer rests with fear of exposure about something. The more he fears exposure, the more he demands secrecy.
Of what we know about him, we know that Trump is absolute about his commitment to hide his tax returns and a full financial disclosure.
What would make Trump flinch? What would make him "obey a command"? It would be a person who holds Trump's most personal, and vulnerable information. The information is Trump's tax and financial records. And that person is Putin.
By now, we should be estimating that Putin's army of computer hackers have breached the security barriers of the IRS and copied Trump's IRS documents, enough of them to have Trump shitting donuts. Now that makes a little bit of sense. Trump's absolute hold on his tax records means that they are the most treasured and private documents he has. What's also true is that they hold information that's criminal in nature. (Just a humble opinion...) And that's why they're the perfect blackmail material. So why wouldn't Putin hold those records over Trump's head and dare him to jump for them?
