In early 2007, Ron Paul, a congressman from Texas, announced his candidacy for the Republican Party's nomination for president of the United States in the 2008 election. Initial opinion polls during the first three quarters of 2007 showed him consistently receiving support from 3% or less of those polled. In 2008, Paul's support among Republican voters remained in the single digits, and well behind front-runner John McCain.

Ronald Ernest Paul is an American author, activist, physician and retired politician who served as the U.S. representative for Texas's 22nd congressional district from 1976 to 1977 and again from 1979 to 1985, as well as for Texas's 14th congressional district from 1997 to 2013. On three occasions, he sought the presidency of the United States: as the Libertarian Party nominee in 1988 and as a candidate for the Republican Party in 2008 and 2012.
