Just wanted to link to this article for easy reference:

Why Government Spending Does Not Stimulate Economic Growth: Answering the Critics

A salient quote from the piece:

"The idea that increased deficit spending can cure recessions has been tested repeatedly, and it has failed repeatedly. The economic models that assert that every $1 of deficit spending grows the economy by $1.50 cannot explain why $1.4 trillion in deficit spending did not create a $2.1 trillion explosion of new economic activity."

Illusion: President Obama and the Democratic leadership in Congress know how to fix the economy.

Reality: They don't. Let's stop sending them to Washington to do the exact opposite of what needs to be done, huh?
