Mike Gravel Retires From Politics

After losing the Libertarian Party presidential nomination to former Georgia congressman Bob Barr, former Alaska senator Mike Gravel has effectively ended his political career.

"I just ended my political career," Gravel said shortly after he was eliminated. "From 15 years old to now, my political career is over, and it's no big deal. I'm a writer, I'm a lecturer, I'm going to push the issues of freedom and liberty. I'm going to push those issues until the day I die."
