Former co-chairman of the President's Fiscal Commission Alan Simpson, a former Republican senator from Wyoming, directly went after no-new-taxes activist Grover Norquist.
NBC's Domenico Montanaro reports on the increased number of pledges and Grover Norquist's influence, in particular, on MSNBC's The Daily Rundown in August.
"If Grover Norquist is the most powerful person in America, he should run for president," the usually locquacious Simpson said. "He has people enthralled."
Norquist's no-new-taxes pledge is a rite of passage for Republican presidential candidates. Each of the 2012 candidates has signed the pledge except former Utah Gov. Jon Huntsman.
Simpson then described how Norquist's favorite president was Ronald Reagan and that Reagan raised taxes eight times.
