It's worth recalling that Chris Christie didn't run on an anti-spending crusade. From Daniel Foster's recent National Review cover story:
Even as Christie beat conservative favorite Steve Lonegan in the primary and surged past Corzine on a wave of anti-incumbent fervor, the state’s small conservative establishment feared they were in for more of the same. Those fears seemed justified, since Christie, despite employing the proper rhetoric about Trenton’s unsustainable “addiction to spending,” was frustratingly vague about his plans to fix the state’s finances, more or less claiming that he had to see for himself how bad the situation was before he’d know what needed to be done. To many, this was the tack of a governor who intended to go along to get along, and who’d be swallowed whole by the Democratic Trenton machine.
And that worked out just fine, didn't it?
