That is very good analysis, and also a good suggestion. Once the Mueller investigation concludes—if it ever does—Trump will have a freer hand. In the meantime he needs a workaround, and your idea is a good one.
I can't help but doubt it. If Trump allows them to endlessly build more of an unfair legal attack against him, especially more arrests of his associates if not family, it's that much more of an attack that he will have to defend and explain. And even assuming he eventually comes out on top, to then try to arrest Mueller or others, he will be faced with just as many saying "in America we don't jail our political opponents after they lose."
Right now the press is doing a good job of keeping the illegal acts of Hillary/Obama and the deep state under wraps. We here at FR know what they did, but I was very surprised when visiting with my strong conservative family members recently how little they did. Trump has got to get that message out, and pull the trigger as soon as possible, to avoid even more collateral damage, if not suffering a critical hit.
Happy New Year FRiend! Hope it's a great one for you and yours.
