EJ Dionne's column on budget trade-offs and priorities is a good read. This president will defend tax cuts by any means necessary. It was one of those moments when a public official gives away a larger truth by offering what seems to be a throwaway line.

Paulson Jr. suggested he would not mind a bit if the Democratic Congress added money to prevent cutbacks in coverage under the federal government's children's health insurance program. "It just may be," Paulson said mildly, "that the Congress believes that that's something that should be funded at a higher level."
