On legal issues alone....
Trump has said he would loosen the Libel Laws to make it easier to sue the press. No good.
“I’m going to open up our libel laws so when they write purposely negative and horrible and false articles, we can sue them and win lots of money,” Mr. Trump said in February. “We’re going to open up those libel laws. So when The New York Times writes a hit piece which is a total disgrace or when The Washington Post, which is there for other reasons, writes a hit piece, we can sue them and win money instead of having no chance of winning because they’re totally protected.”
Trump said in a debate, Judge Alito signed a bill. Judges do not sign bills.
Said in a debate that Senator Ted Cruz of Texas had criticized Mr. Trump’s sister, a federal appeals court judge, “for signing a certain bill,” adding for good measure that Justice Samuel A. Alito Jr., while still an appeals court judge, had also “signed that bill.”
But bills are legislative rather than judicial documents. And, as it happened, Judge Alito had not joined the opinion in question.
Trump does not understand the Judicial branch.
Trump says he would appoint Judges who who would prosecute
“probably appoint people that would look very seriously at” Hillary Clinton’s “email disaster because it’s criminal activity.” In the constitutional structure, however, Supreme Court justices are neither investigators nor prosecutors.
Mr. Trump has boasted that he will use Mr. Obama’s actions as precedent for his own expansive assertions of executive power.
“He’s led the way, to be honest with you,” he said in January on “Meet the Press,” referring to Mr. Obama’s program to spare millions of immigrants in the country unlawfully from deportation. “But I’m going to use them much better, and they’re going to serve a much better purpose than what he’s done.”
I won't even mention the flip-flops, anger issues, etc.
