“The tax issue is the most powerful issue in American politics going back to the Tea Party. People say, 'Oh, Grover Norquist has power.' No. Grover Norquist and Americans for Tax Reform focus on the tax issue. The tax issue is a powerful issue.”

American political activist and anti-tax advocate

Grover Norquist is an American political activist and anti-tax advocate. He is the founder and president of Americans for Tax Reform, and has been a prominent Republican voice in fiscal politics. He is best known for promoting the Taxpayer Protection Pledge, a commitment by lawmakers to oppose tax increases, including higher marginal rates and changes that cut deductions or credits without offsetting rate cuts. Before the November 2012 election, the pledge had been signed by 95% of Republican members of Congress and by all but one candidate for the 2012 Republican presidential nomination.
