The court cases so far have done nothing but turn Trump into a martyr. They're civil cases in deep Blue places like NY and DC that have been perceived as biased political persecution and will likely be overturned or severely reduced in appeal. The old bimbo that claimed sexual assault is hardly credible, and did herself no good by launching her "victory shopping tour" on MSNBC. The real estate case just concluded in NY was based on an obscure never-used fraud statute and decided by a highly biased judge and corrupt prosecutor. Everyone but the Trump haters and deluded liberals can see this was not a fair trial or reasonable penalty. It's human nature to be repulsed by contemptible people in power who abuse the legal system to destroy people like Trump or anyone else.You are placing a lot of faith in Trump's coattails; the coattails of a man who cannot fill a rally like he used to, and who is racking up one loss after another in court.
It's no wonder Trump's ratings go up every time he loses a case people perceive to be rigged. This will continue until he is actually convicted of a legitimate felony charge in a fair court by an unbiased jury. Until then his following will continue to grow.
