Historically any congress can affect the economy by its actions in 18 to 24 months. What policies they put in process will affect the economy. SOmetimes can take longer. Regulations can be a big factor affecting the Economy. YOu can not regulate an economy into success but you can Regulate the economy into a recesson or even a Depression. FDR regulations and new deal Programs extended the depression a decade longer than it need to be. So what congress does does matter. And the president by the policies he pushes can affect the economy. More regulations from EPA to shut down sectors of the economy can hurt everyones pocket book. But Al Gore must love it because he wants $5/gal gas. And that in 90's Dollars.
