Moderate Republicans in the Senate have been hollering in recent months that we need new budget rules to restrain tax cuts and spending. Any tax cuts or spending increases will have to be paid for by tax increases or spending cuts elsewhere. Except that it turns out that they’re willing to waive the rules on the spending side. McCain, Snowe, Chafee, and Collins all voted today to allow $8 billion in new unemployment benefits with no offsets. They seem less interested in shrinking the deficit than in enlarging the government.
