Sometimes people get so wrapped up in "their Team" that they cannot think straight. Look at Footbol fans around the world. Going apeshit bananas over a 1-0 match. The match is more about National Pride and Patriotism than it is about the competition on the field.
So in America, when it comes to Politics, people argue for "their Team" regardless of right and wrong. Most Americans sadly think it's all about "winning" and defeating the other side like it's some kind of sports match. But it isn't. It should be about working together to make the country better. But nope. Both sides fight and argue trying to "win"...what exactly? What is the prize exactly? A "better America"? Ridiculous nonsense.
Geez, at least in a sporting event you get an actual winner/loser, some prize money and a fucking ring or medal.
