Well, that's simple. Byrd was a politician, life-long...he would do and say anything to get, keep , and maintain power. If politics demanded that he wear a tutu, he would wear a tutu. If politics demanded that he wear his underwear on the outside of his suit, you could count on him showing up with his tightywhities in plain view. If politics demanded that he publicly denounce his mother as a New Orleans w**re, you guessed it, he would call her Lulu White, the madam of Storyville. He would sell his soul to the devil to stay in power.
Trump won't. He just keeps on being himself, unapologetically.
