I think Dr Paul has done very well keeping his oath by discharging his duties.
"I do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God."
There is definitely a formal leadership team in the House who can count on Ron Paul being a rogue. You have heard of the Speaker of the House, majority and minority leaders, majority and minority whips, etc., right?
