The liberal program writ large since the sixties has been a disaster. But liberals don't think that. They think they've had huge successes culminating with the Clinton years who of course enacted a number of successful laws that were originated by conservatives (welfare reform, tax reform) ...because The Great Fornicator knew that liberalism is bunk but couldn't admit it for obvious reasons. They think the only reason their programs aren't more successful is because stingy conservatives cut the money supply or killed their "successful" programs. Even after liberal program after liberal program was proven to be a disaster, they still believe in liberalism. Results don't matter to libs, only intentions.
Welfare reform was signed by Clinton (even if it was watered down), but "tax reform"? Not during Clinton. The only thing we got from Clinton (who was elected in part on his lie to support "middle class tax cuts") was the largest tax hike in history.
It was Dubya who came along and cut taxes. That's why tax revenues to the federal government are now soaring, the deficit is coming down fast, and the economy is chugging along better than ever.
