Citizens for Tax Justice has released A Congressional Tax Report Card:

Over the past six years, Congress and President Bush have made major changes to the federal tax system, dramatically affecting tax fairness, revenues and budget deficits. This Congressional Tax Report Card looks at the five key tax votes in the House and Senate that have produced these changes, plus one additional vote on an important recent tax bill that Congress narrowly rejected:

1. The Economic Growth and Tax Relief Reconciliation Act of 2001
2. The Job Creation and Worker Assistance Act of 2002
3. The Jobs and Growth Reconciliation Tax Act of 2003
4. The American Jobs Creation Act of 2004
5. The Tax Relief Extension Reconciliation Act of 2006
6. The Death Tax Repeal Permanency Act of 2006,”

The Tax Report Card details how members of Congress voted on these six bills, and grades each member on the combination of his or her votes. The grading system is based on the combination of two criteria: tax fairness and fiscal responsibility — principles that all sides of the political debate at least pretend to honor.

Those who voted "Yes" received an "F" grade; those who voted "No’ received an "A" grade. 253 members of Congress (209 House, 49 Senate) voted "Yes" on all six bills and received an overall "F" grade; 157 members of Congress (138 House, 19 Senate) voted "No" on all six bills and received an overall "A" grade.
