Bob Barr is a former Republican U.S. House Rep for the 7th District in Georgia as well as a former Presidential candidate under the Libertarian Party ticket. Mr. Barr, an attorney by profession, has also been involved in defending those who find themselves persecuted simply for exercising their Second Amendment rights. He also writes a column for the Atlanta Journal Constitution.
When Barr was in Congress, it would be fair to say he was less interested in protecting the privacy of ordinary Americans by voting for the Patriot Act and authoring DOMA. However soon after leaving Congress he has been a champion of privacy rights and admits DOMA was mistake.
Mr. Barr has been rumored to be mulling the idea of running for U.S. Congress, probably as a Republican instead of as a Libertarian Party candidate.
