Congressman Ron Paul (TX-R) is considering a run for the presidency. He previously ran for president in 1988 as a Libertarian. He is noted for being a Republican who voted against the 2003 invasion of Iraq. If Paul wins the GOP nomination and Hillary Clinton wins the Democratic nomination, 2008 will be a contest between an anti-war Republican and a pro-war Democrat. This will really make a lot of people switch parties, and it will be even more divisive than 2004.
