As much as I'm offended by many of the things Ron Paul does and stands for, I'm glad he's there. There's a lot of divergent thinking there. Outliers are good. I'd be terrified of a congress with a dozen Ron Pauls, but one is good to have around.
If I had my druthers, we'd have one of him in Congress. And one of each other extremist point of view, left-wing, right-wing, or just off in another direction.
If American politicians had no outside interests than sure. It's currently a fundamentally flawed system: political games, corporate interests, religion and re-elections all cloud actual discussion and turns it into a show.
Nothing in house is driven by real data, both sides don't see the actual reality of what ever situation they're in. They take random data points to mislead voters to their position, each side having different areas they fudge the numbers on.
