When the house of cards began falling down around Richard Nixon, some Republicans felt like, "This is our guy; we have to protect him!" while other Republicans felt like, "We don't want the world to judge us by what this guy does!"
As the case developed, there came a secret meeting among senior Republicans in the Senate about whether or not they would prevent Nixon's removal from office should he be impeached, which seemed like it was almost certainly going to happen soon. For the good of the party and the good of the nation, they sent a message to Nixon through Kissinger: The Senate GOP would not protect him. 48 hours later, Nixon resigned.
Better legal minds might feel differently, but to my way of thinking, what happened on Jan 6 was vastly more serious than when Nixon was president. The difference is how the rest of the GOP responded and how the president himself responded. Nixon could have fought it. He could have done everything Trump is doing now, but, in the end, Nixon was the better man.
I honestly admire Nixon. I always have. He was every bit as great as he was broken. After Nixon, there grew a strong feeling among Republicans that they had made the wrong decision. That feeling grew, especially when Carter beat Ford. That's when Reagan came up with this idea of "Never speak ill of another Republican." That philosophy is dominant now. No matter what a Republican does, their party won't turn on them.
Ultimately, I'm not a party kind of guy. Adherence to your party, no matter what they do, might work for football fans, but it's a very bad idea when it comes to governance. There have been, and are now, some really shit Democrats. I'll be glad to talk to you about them. For the most part, though, I'm still going to vote Democrat when it's a decent guy because (right now) their platform is better for Mississippi. That could change, but right now, it's overwhelmingly clear to me that Mississippi, my home, is better served by what the Democratic party brings.
When a great man rose in Rome, and he took his triumphant chariot ride through the masses singing his name, there stood a man behind him, a slave called an "Auriga" whose job it was to hold a wreath of laurel above his head, but whisper in his ear, "remember, thou art but a man." We could use some of that today.
