Here is my opinion of why Trumps is suing Hillary.
First -----Payback is a bitch.----and he wants it bad. And I don't blame him.
Next, He knows that there will never be a criminal charge against any of them
People in that strata never get charged with Treason, Fraud, Corruption or anything less than murder---and sometimes not even that. I believe we all have enough experience with Hillary , Bill , Kerry, Hunter, Old Joe, et.al. to realize that
Yet in Civil court he might hurt them where they live. In the pocketbook.
Yes I would love to see Hillary in Jail, Kerry and Jane Fonda shot for Treason and Biden and his pedo son behind bars. But we all know it aint gonna happen.
But a huge settlement in these lawsuits is the closest we will ever get to Justice.
