I’ve never seen anything indicating causality between the 2007-2009 Pelosi Comgress and the recession. Correlation yes, but not causation.
The recession was caused by the CRA poison pill pushed through by Dems years before and the massive over leveraging of Fannie Mae and Freddie Mac. There was a massive, unsustainable bubble in housing, made worse by It being the sector investors fled to when the dot com bubble popped.
The recession really had little to do, directly, with the Bush tax cuts or whatever level of supply side was in effect when the housing bubble popped. This article is just Monday morning quarterbacking by someone seeking to point fingers and push an ideological agenda.
There are obviously a trillion and one different inputs into the economy, so one particular cause or another of a recession will always be hard to establish, but I don’t think it’s pure coincidence that the economy started to head south soon after the Dem’s took over Congress and as polls began to make it increasingly clear that they would soon take over the White House as well. I think business owners, investors and consumers all make decisions based on the available information about what’s coming down the pipe, and socialism is what they saw coming in 2007 and 2008.
