Because it lies

Some excerpts from an interesting essay:

On Nov. 21, Newt Gingrich, who is leading the race for the Republican presidential nomination in some polls, attacked the Congressional Budget Office. In a speech in New Hampshire, Mr. Gingrich said the C.B.O. “is a reactionary socialist institution which does not believe in economic growth, does not believe in innovation and does not believe in data that it has not internally generated.”  

[...] 

Mr. Gingrich has long had special ire for the C.B.O. because it has consistently thrown cold water on his pet health schemes, from which he enriched himself after being forced out as speaker of the House in 1998. In 2005, he wrote an op-ed article in The Washington Times berating the C.B.O., then under the direction of Mr. Holtz-Eakin, saying it had improperly scored some Gingrich-backed proposals. At a debate on Nov. 5, Mr. Gingrich said, “If you are serious about real health reform, you must abolish the Congressional Budget Office because it lies.” 

This is typical of Mr. Gingrich’s modus operandi. He has always considered himself to be the smartest guy in the room and long chaffed at being corrected by experts when he cooked up some new plan, over which he may have expended 30 seconds of thought, to completely upend and remake the health, tax or education systems.

Because Mr. Gingrich does know more than most politicians, the main obstacles to his grandiose schemes have always been Congress’s professional staff members, many among the leading authorities anywhere in their areas of expertise. To remove this obstacle, Mr. Gingrich did everything in his power to dismantle Congressional institutions that employed people with the knowledge, training and experience to know a harebrained idea when they saw it. When he became speaker in 1995, Mr. Gingrich moved quickly to slash the budgets and staff of the House committees, which employed thousands of professionals with long and deep institutional memories.
