In all three criminal cases, Grand Juries in Washington D.C, Georgia, and Florida, have determined from the evidence presented that there were crimes committed and evidence pointed to Trump.when charges are dropped because there is no evidence of a crime, the judges are not corrupt, they are honest. The cases you mentioned are all fake, they are nothing but political moves to try to keep Trump from winning in November. And why are the dems and libs so scared of a second Trump term? any idea? because they know that he will expose and prosecute their long term corruption and treason. The fear of conviction is why they are so bent on destroying Trump. Wake up and smell reality.
Federal judges may dismiss an indictment if unnecessary delays occurred but will not dismiss an indictment for lack of evidence. That can only happen if the defense files a motion before the trial. If a federal judge is going to dismiss an indictment, he or she will do so before scheduling the trial. That time has passed in all these cases. So Trump's defense is trying to delay the trial till after the election. Once Trump is elected he will shutdown the federal cases immediately. The state cases could continue but it is very unlikely a sitting president will be tried and if he is he'll just ignore it.
The only way to insure that Trump faces trial is if those trials occur before the election and that's looking unlikely with the exception of the New York criminal trial.
