Here's a rousing defense of the Bush tax cuts by Donald Luskin in The Detroit News: www.detnews.com/2004/editorial/0408/27/a09-255537.htm. (For the record, I found the link to this article at Polipundit.com).
Don't take Luskin's word for it, though. You can check out the Congressional Budget Office's analysis yourself: www.cbo.gov/showdoc.cfm?index=5746&sequence=0&from=0#anchor.
