But Byrd and current Democrats don't hold those views now. For his part, Paul argues that a 1964 law would not be relevant to issues he'd face as a senator. But that's not exactly right. The questions about his views on the Civil Rights Act grow out of his present-day views about limits on government intervention. That's always an issue in Washington, especially right now, as the Senate debates a bill to regulate financial institutions. At its core, it involves the question of just how far government can go to regulate private enterprise.
