How hard is it to figure out McConnell?

His #1 priority is getting then keeping power. Morality is way down his list of priorities. Which means that if Trump becomes the Republican presidential nominee in 2024, OF COURSE McConnell will support him because a Republican POTUS means more power for Senate Republicans.

McConnell doesn't have to be amoral or immoral. He just needs to prioritize power over morality. Which he does. In spades.
