If Hillary goes down, she may take BO with her. I’ve long thought that the Clintons and Obama are like two scorpions in a box. They each have something big on each other. I believe the Clintons know BO’s history and have the documents to prove it.
That is how she became so "powerful" by keeping track of everyone. Stealing files and ever it takes to have leverage over them. She wouldn't take anyone in unless they had something to hide.
Trump was never in politics and had a reasonably clean record. She had nothing on him.
