John Stossel's latest column posted by the Washington Examiner explores Texas congressman Ron Paul's influence on the current American political scene. Paul is always upbeat, but lately he's had more reason to be, as he sees libertarian ideas bubbling up from the grass roots. "People outside of Washington are waking up," he told me, "and they're getting the attention of a few in Washington." Paul has been in Congress more than 20 years, and much of that time he's played a lonely role, often being the only representative to cast "no" vote on bills to expand government. "Twenty years ago, there weren't very many people around that would endorse these views. So ... I'm very pleased with what's happening. There are more now, but the problems are so much greater."
