I'm not so sure the left will follow precedent and leave Trump and company alone.
I should clarify that I don't believe he will be left alone. Hence my statement that it will cost him more to defend himself. He'll be hounded more than any other previous President, but they won't win in court. It'll just be the equivalent of the crummy neighbor who instigates nuisance lawsuit after nuisance lawsuit.
I was hoping with Trump's legal team and his own personality, that he will turn the tables and maybe make the attackers the attacked. If a few of them end up paying out a few million dollars, the rest might eventually back off.
If Trump were prosecuted for ANYTHING while Hillary Clinton walks free, that's the line for a lot of people. The left better be careful what they wish for.
