The one major desire of the Republican Party, ie to make government smaller, is clearly NOT a concern of The Donald.
Trump is simply returning to the idiotic "Law and Order" theme of Nixon.
Most crime is local and is dealt with by municipal, county and state authorities, What would Trump have done to prevent the Pulse nightclub massacre or the shooting of cops in Dallas? The President has nothing to do with preventing, prosecuting or punishing such crimes. What could any president do to prevent some suicidal nut with a bomb or an assault rifle?
When Trump says he knows how the system works, he isn't lying. The President makes a promise, discovers that he has no authority to deal with the issue and blames the Congress or state and local laws for his inability to do anything. It's like promising a beautiful condo, selling shared of it and then keeping the deposits and bailing out with nothing ever being built.
No president has the authority that he thinks he has before he is elected, A huge number of voters think they are electing a king or some other sort of despot with omnipotent powers, despite all past evidence that this is false.
President Obama thought he could close Guantanamo, because it makes perfect sense to do so: it costs a million dollars a year per prisoner compared with $25,000 at most in a maximum security prison in the US. But Congress turned it into a political football and the President can't do anything, through no fault of his own, becaue Congress refuses to fund moving the prisoners.
If a president cannot close a federal prison, then how much power does he actually wield? Certainly not enough to do even a small fraction of what The Donald promised. The GOP platform was as anti-LGBTQ document as has ever been agreed to by any party, yet Trump says her will defend all the LGBTQ people as no president ever has before. Does he have the power to station federal agents at the door of every gay club in the nation? How can a president stop a suicidal nut with an assault rifle or a bomb?
Trump is a fraudster trying to sell us on another of his bogus deals.
