Republican presidential candidate Herman Cain's 9-9-9 tax plan has taken a lot of heat recently. One of the biggest criticisms: several independent analysts have found that under the plan, poor and middle class families would pay higher taxes while the richest of the rich would see a substantial tax cut. Today in Detroit, Cain unveiled his response.
"If you're at or below the poverty level, your plan isn't 9-9-9," said Cain with the abandoned Michigan Central Station in the background. "It's 9-0-9."
