2. Why is he running?
â€śBecause heâ€™s got things he wants to say and he doesnâ€™t think anybody else in the race is going to say them,â€ť says David Boaz, executive vice president of the libertarian Cato Institute in Washington, D.C.
As a candidate most analysts describe as a long shot at best, Johnson is running to bring attention to issues he deems important, adds Wes Benedict, executive director of the Libertarian National Committee.
â€śI wouldnâ€™t bet he has a chance to win the Republican nomination in 2012, but I think he has a chance to make a change in public policy,â€ť says Mr. Benedict.
