Norquist: Cain's 9-9-9 tax plan like having 'tapeworms'

Grover Norquist, president of Americans for Tax Reform, called GOP presidential candidate Herman Cain’s 9-9-9 tax reform plan “very dangerous,” likening the proposal to “tapeworms.”

“To put tapeworms in your tummy to try and maintain your weight — they may have their own idea about their growth patterns and what they want to do. Creating new taxes is a very dangerous project,” Norquist said on ABC News's "Top Line" on Monday.

Cain's proposal calls for replacing the current tax code with a 9 percent income tax, 9 percent corporate tax and 9 percent sales tax.

Norquist, a prominent anti-tax advocate, said there could be troubling consequences from adopting Cain's plan. He said it was unlikely that taxes would stay at 9 percent, claiming that lawmakers could increase the rates leaving voters with a “10-10-10” tax rate or worse.

Cain's proposal has been controversial, with some critics claiming the plan would place a higher tax burden on working-class families.
