I never under-estimate Donald J Trump. He has been through more courts than you can shake a stick at, and has come out ahead. He has been through divorce courts, bankruptcy courts, numerous suits in his real-estate business, attacks on Trump university, etc. He has prevailed through all of that.
I agree. This time though there are a whole lot more people going after him. I'm sure he will survive, but along the way, they will put a lot of "stink" on him & a lot of doubt in some voters' minds.
If there is a "plan" going on behind the scenes, I hope it goes into motion soon.
