New York Magazine has a good article explaining why the Stormy Daniels hush money is a particularly bad case to bring against Trump, especially since as the FIRST criminal case it will set precedents. When these charges are thrown out, his supporters will gain strength and enthusiasm.
Adultery is not a crime; paying hush money is not a crime. If Trump were not a candidate and paid the hush money to protect his reputation for his TV show, that would not be a crime.
If Trump WERE a candidate, assumed he would lose, but wanted to protect his TV reputation, the hush money would still not be a crime. Prosecutors would need to prove that the intent of the hush-money was to support his bid for President -- and even then we're talking about just a "technical" violation. It would be very hard to get 12 jurors to convict if the defendant were an unknown; given wide sympathy for T****, acquittal seems all but certain.
He may also be charged with falsifying records, but this is an uncertain ambiguous charge. And is only a misdemeanor charge anyway (unless the falsification was to abet a separate crime).
There are half a dozen prosecutors pursuing T**** for several crimes, all more serious than the Stormy affair. Ideally they should work together and coordinate timings for best effect. Instead, are the prosecutors just playing like prima donnas?
