I guess they are so twisted with hate that it never occurred to them that a billionaire New York businessman might have some of the best tax lawyers in the country on his payroll. Idiots. Add to that the fact that we already know they had several years of backdoor access through their "helpers" at IRS. There is no way they didn't have a long, careful look into all aspects of his finances, taxes, everything.
Anyone who disputes that is an idiot after all of the leaks we saw during his presidency. If he wins again, these thugs are going to try to burn it all down to keep him out of the office. Up until a year or so ago I thought those who were talking about civil war were alarmists and not very bright. Today, I see it much more clearly. They proved with their perpetual investigations and accusations and legal gambits that they will do ANYTHING it takes to stop him. In fact, I think we might well see the violence begin before he even has a chance to win again. After all they've tried and failed with, they are apt to become unhinged. IF they take that step, there will no longer be any doubt that our nation has been attacked from within and at that point, these crazy bastards will find they aren't going to be in the streets alone.
