There was a time when Republicans raged against wasteful federal spending and fought tenaciously to cut the size of government. Not any longer. The $286.5bn (£160bn) highways bill President George W. Bush will sign into law today epitomises the transformation of the party in Washington from an anti-government "insurgency" into a ruling majority unable to kick its addiction to spending.

To give Mr Bush his credit, he fought a rearguard action against his spendthrift allies in Congress, with some effect. But he did not follow through his threat to veto any bill that breached a $283.9bn spending limit. This was itself a big increase on the spending limit of $256bn he put forward a year earlier. Budget analysts estimate the true cost of the new law, which conceals some likely spending, may be as much as $11bn over the relaxed spending limit.
