Quotations about:
    term limits

In the midst of all my bitching, you might’ve noticed that I never complain about politicians. I leave that to others. And there’s no shortage of volunteers; everyone complains about politicians. Everyone says they suck.
But where do people think these politicians come from? They don’t fall out of the sky; they don’t pass through a membrane from a separate reality. They come from American homes, American families, American schools, American churches, and American businesses. And they’re elected by American voters. This is what our system produces, folks. This is the best we can do. Let’s face it, we have very little to work with. Garbage in, garbage out.
Ignorant citizens elect ignorant leaders, it’s as simple as that. And term limits don’t help. All you do is get a brand new bunch of ignorant leaders.
