Obviously, Trump’s premise that he is being prosecuted by Joe Biden because he is running against him is false. Trump is being prosecuted because he is a career criminal, and there is no evidence any of the prosecutors taking him to court have communicated with President Biden.
But beneath this first lie, there’s a second lie: Trump only intends to prosecute his political enemies because they did it to him first. In fact, Trump has been planning to lock up his political opponents since he first ran for office, well before any of the current prosecutions began.
Less wild than you might think. "Law and order" is a dog whistle that's been around long enough that people who don't understand it have started using it. Law and order means using the state's monopoly on violence to maintain existing social hierarchies, and when you understand this, the actions of the people who champion "law and order" makes a great deal more sense.
