How would Ron Paul get Congress to go along with his agenda?

Presidential power is the power to persuade — Congress, the media and ultimately and most important, the American people. The power of the purse, meanwhile, resides on the other end of Pennsylvania Avenue.

Paul has been in Congress, off and on, for nearly 30 years. In that time, he will rightly tell you, Congress has spent money with reckless abandon, expanded the state’s police powers, launched numerous wars without a declaration of war and further embraced fiat money (he got into politics when Richard Nixon took us fully off the gold standard). During all of that, he took to the floor and delivered passionate speeches in protest convincing … nobody.

Paul’s supporters love to talk about how he was a lone voice of dissent. They never explain why he was alone in his dissent. Why couldn’t he convince even his ideologically sympathetic colleagues? Why is there no Ron Paul caucus?
