Krugman today:

"There is no longer any doubt that the man who ran as a moderate in the 2000 election is actually a radical who wants to undo much of the Great Society and the New Deal.

Look at it this way: as the Center on Budget and Policy Priorities points out, this latest tax cut reduces federal revenue as a share of G.D.P. to its lowest level since 1959. That is, federal taxes are now back to what they were in an era when Medicare and Medicaid didn't exist, and Social Security was still a minor expense. How can we maintain these programs, which have become essential to scores of millions of Americans, at today's tax rates? We can't."

And again...where's the debate?
