Bob Barr for president?

According to the Washington Times, the former Republican congressman from Cherokee County confirms he is considering a run for president as a Libertarian.

"There is great deal [of] dissatisfaction with the candidates for the two major parties, particularly among conservatives, but also a great deal of Internet and other support for a candidate like Ron Paul who advocates libertarian and true conservative principles," Barr, who is now a Libertarian, told the newspaper.

Paul, a Republican candidate this year, was the Libertarian presidential candidate in 1988. The Times said Barr declined to say whether he had been approached by Paul about a presidential bid.

If Bob Barr were to run he would have my vote.
