WATCH: New McCain ad - ' Enough is Enough'
One day after the biggest drop on Wall Street since just after the Sept. 11, 2001 terrorist attacks, Republican presidential candidate John McCain launched a cable TV ad in Iowa and across the country.
"The economy is in crisis. Enough is enough. I'll meet this crisis head on," McCain says. "Reform Wall Street. New rules for fairness and honesty. I won't tolerate a system that puts you and your family at risk. Your savings, your jobs ... I'll keep them safe."
