Trump was being consistent with his practice of never giving away anything until he can trade it for value. He needed every vote he could get, including votes from people who think and do things you and I don’t like. If that sounds terrible to you, keep in mind that Trump’s background is the construction business in New York. He has dealt with unsavory characters. And sometimes those unsavory characters are a small part of a larger plan for a greater good, whether you hate them or not. You can make up your own mind about the ethics of using bad people to get good outcomes.
