Ron Paul talks war, spending, drug policy

In his third go-around as a presidential candidate, Paul said he feels his priorities to bring home American troops, enact a humble foreign policy and drastically cut federal spending will reach many voters who share similar concerns.

"People are coming around saying, 'Hey, what we're doing now isn't working,'" said Paul. "It hasn't worked because it can't work."

On the wars the United States is currently involved in, Paul said pulling troops out of such locations would be one of his first actions if he is elected to office.
