Here's what the National Bureau of Economic Research, a large private economic research organization, has to say about US Business Cycle Expansions and Contractions: March 2001 to November 2001. Previous recession was under W's Daddy's watch: July 1990 to March 1991. There was no Clinton recession.

The whole myth of a Clinton recession was Republican political strategy according to this 2004 Business Week analysis, Inventing The "Clinton Recession".

President George W. Bush's Council of Economic Advisers, chaired by Harvard economist N. Gregory Mankiw, is trying to get away with exactly such revisionist history. The CEA's Economic Report of the President, released Feb. 9, unilaterally changed the start date of the last recession to benefit Bush's reelection bid. Instead of using the accepted start date of March, 2001, the CEA announced that the recession really started in the fourth quarter of 2000 -- a shift that would make it much more credible for the Bush Administration to term it the "Clinton Recession." In a subsequent press conference, Mankiw said that the CEA had looked at the available data and "made the call."

To be fair, even if the latest recession did begin after Bush took office in January, 2001, no one can say he caused it.

I can. Bush caused the recession. He caused a fundamental shift in the direction of the United States from the Clinton administration. The selection of Bush caused the recession. In fact, I'd argue that if Gore became president, the U.S. and the world would have missed a recession by a massive move toward a green economy. Instead the U.S. Supreme Court made the choice to disaster capitalism and the looting of the U.S. economy began in earnest. Additionally, Gore likely would have focused on counter terrorism and the attacks in the U.S. on 11 September 2001 may have been thwarted.

Bush caused two recessions. His first recession, in 2001, will be considered mild compared to the abyss he's opened up beneath the U.S. economy in his final term.
