The most powerful figure in today's Republican Party is not John Boehner or Mitch McConnell. It is not Mitt Romney or Paul Ryan. It is not even Rush Limbaugh or Sarah Palin.
It is, of course, Grover Norquist, the man with The Pledge.
Norquist, who has never held elected office, is the founder and president of Americans for Tax Reform, a group whose pledge not to raise taxes under any circumstances has now been signed by hundreds of Republican candidates and officials at both state and national levels.
And they do mean "any circumstances." Enormous budget deficits? No. A country at war? Nope. Famine and plague? Sorry.
Our grandmothers kidnapped and threatened with death until and unless we raise taxes, as Norquist was asked recently by Stephen Colbert? Well, answered the unflappable Norquist, we always have our memories and our photographs.
(Colbert was being characteristically satiric. There appeared to be nothing satiric about the response.)
I want to set aside for now the political and economic wisdom of raising or not raising taxes and focus instead on an even more fundamental question: How prudent is it to take an irrevocable pledge about how to govern before one begins the actual work of governing?
How wise is it to remove from the legislative toolbox one of the most important tools before one knows what particular challenges one will face?
