First, by trying to do everything all it once, the bill does nothing well. The money spent on long-term domestic programs means there may not be enough to jolt the economy now (about $290 billion in spending is pushed off into 2011 and later). The money spent on stimulus, meanwhile, means there’s not enough to truly reform domestic programs like health technology, schools and infrastructure. The measure mostly pumps more money into old arrangements…

Third, the muddle assures ideological confrontation. A stimulus package was always going to be controversial, because economists differ widely about whether or how a stimulus can work. But this bill also permanently alters the role of the federal government, thus guaranteeing a polarizing brawl at the very start of the Obama presidency.
