Why has Grover Norquist visited the Bush White House at least 155 times?

Today's New York Times reports that Grover Norquist has visited the Bush White House at least 155 times.

Sleazy Abramoff-related lobbying? Surely you jest. According to the article, "White House spokeswoman Dana Perino said ... [that] it was possible some of Norquist's meetings were with Karl Rove, the president's longtime confidant and political strategist.

"'He is one of a number of individuals who worked to advance fiscal responsibility, which is one of the key aspects of the president's agenda,' Perino said."

Grover Norquist is to fiscal responsibility as Jack the Ripper was to safer working conditions for London prostitutes.
