This is typical of people who don't know beans about politics. He probably really doesn't realize what he is on the political spectrum.
They say things like "they ALL do it", "they ALL lie", "they're ALL crooks". Being politically ignorant makes a person very gullible to exotic conspiracy theories, they generally seem more comfortable with crazy notions then with logical, sensible opinions.
Actually he is really well informed and educated. He just hinks there is a one world orde that is in control of everything, or nearly in control of it, and it doesn't really matter, it is all fixed. But of course, it is mostly the evil republicans and conservatives who are running things.
