Republicans say these things to each other when they think they are alone. To them, it is as indisputable as the existence of the air around them. I have to conclude that they really believe this.
Strangely, in the same way, Democrats say EXACTLY the same things about Republicans. I have to conclude that they truly believe this too.
Even something as apolitical as the measure of charisma cannot be agreed upon. Personally, Clinton, Bush, Obama, and McCain all struck me as rather charismatic. On the other hand, Gore, Kerry, and Romney did not. That has absolutely nothing to do with whether I liked their policies or whether I voted for them. Everyone should agree, right? Oddly, I have met people who thought that Romney was charismatic, people who thought that Gore was charismatic, and people who thought that Bush was not.
Sometimes it feels as if I've stepped into bizzaro world, and when we can't even agree on the background reality, it makes constructive debate difficult.
