Mike Gravel came in fourth in delegate votes for the Libertarian Party presidential nomination in 2008, behind Bob Barr, Mary Ruwart and Wayne Root. Before that, he ran in Democratic Party primaries for President that same year, and served as a Democratic US Senator from Alaska from 1969 to 1981. Accoring to wikipedia,
