Ralph Hall (b. May 3, 1923) is a United States Representative from the Fourth Congressional District in Texas. First elected in 1980, Hall is a senior member of the Committee on Science and the Energy and Commerce Committee.
In January 2004, Hall announced his intention to switch from the Democratic Party to the Republican Party. Hall has always been very conservative, crossing party lines on votes and even endorsing George W. Bush's presidential campaign in 2000, so this move comes as no surprise to many observers.
