In 1984, Ron Paul chose to run for the U.S. Senate instead of re-election to the House, but lost the Republican primary to Phil Gramm.
He returned to full-time medical practice and was succeeded by former state representative Tom DeLay. In his House farewell address, Paul said, "Special interests have replaced the concern that the Founders had for general welfare. Vote trading is seen as good politics. The errand-boy mentality is ordinary, the defender of liberty is seen as bizarre. It's difficult for one who loves true liberty and utterly detests the power of the state to come to Washington for a period of time and not leave a true cynic."
