Republican presidential candidate Herman Cain's 9-9-9 tax plan has taken a lot of heat recently. Several independent analysts have found that under the plan, poor and middle-class families will pay higher taxes. And what's more, they say, the richest will see a substantial tax cut.

HERMAN CAIN: Nine-nine-nine means jobs, jobs, jobs.
KEITH: Cain stood before a giant, abandoned building - a symbol of urban blight and decay - to roll out the details of his plan to help distressed inner cities and poor people. For the poor, income taxes would be zeroed out.
