LAS VEGAS — Republican presidential candidates came out swinging at the eighth GOP debate today, and many of their jabs were aimed at Herman Cain's tax plan that includes a 9 percent national sales tax.
Another target early in the debate was Obamacare, which took hits from several of the candidates, who shouted at each other and tried to drown each other out in the debate on CNN.
Former Massachusetts Gov. Mitt Romney and Texas Gov. Rick Perry went head to head, as did Romney and former Pennsylvania Sen. Rick Santorum as CNN moderator Anderson Cooper tried to maintain order.
Several times, one candidate or another asked Cooper to silence a rival.
Rep. Michele Bachmann of Minnesota said during Tuesday's GOP debate that there's no reason why a future Congress and president couldn't raise that to 90 percent.
Santorum said 84 percent of Americans would see a tax increase under Cain's plan. He cited an independent analysis from the Tax Policy Center.
Romney said he likes Cain's boldness but his plan would raise taxes on the middle class.
Cain defended his plan and said it is a jobs plan that wouldn't add to the national debt. He said the plan faces criticism because it challenges the status quo and his rivals don't understand it.
