The Republicans' majority in the House means they have a mandate against raising taxes, Grover Norquist, president of Americans for Tax Reform, told CNBC's "Squawk on the Street" on Thursday.
"We just elected a Republican House that has been elected repeatedly with almost all of them making a written commitment to their constituents not to raise taxes," Norquist, long an advocate for tax reform, said. (Read More: Boehner Extends Olive Branch on 'Fiscal Cliff.')
He said that gives them more of a mandate than President Barack Obama, who was re-elected with only a 2 percent margin and 9 million fewer votes than in the last election.
