Senate and House Republicans, as well as Trump supporters, don't care if he broke laws or engaged in extortion. They don't mind that he turns his back on our allies, cozies up to dictators who assassinate their citizens and who most definitely don't believe in democracy, or tells lies on a daily, prolific basis. It must be because they don't care about truth or morals or respecting the constitution (unless a Democrat is in power, and then it's suddenly important to them). They don't care if he hires white supremacists or homophobes to direct policy or if nearly everyone who surrounds the president is implicated in crimes or quits because they can't in good conscience work for such a corrupt administration. They don't care if rogue soldiers commit atrocities-in fact, many go on to cheer when these war criminals are pardoned. They don't mind if the president says former POWs are not heroes because true heroes "don't get caught". That's because they don't really value the actual sacrifices made by principled and loyal soldiers, no matter how loudly they scream when black athletes take a knee. They obviously don't mind that the same person who said POWs are not heroes never served because he paid someone to manufacture a bogus physical condition to help him avoid service.
The only reason I can come up with for why so many people are not only tolerant of this man, but support and cheer any act of this president, no matter how despicable, is that they share these values. Many must also be racists, homophobes, and selfish isolationists; they must be people who go about their lives "taking liberty with the truth" on the regular, so none of this seems out of whack to them. There is no way a person could be okay with all of this unless they are also lacking in the same principles of honesty, morality, and humanity. Like attracts like, and here we have our reason why anyone would support an administration that so brazenly engages in lawlessness, corruption, hypocrisy, and greed.
