The new situation will reopen old rifts in the Democratic Party. One the one side, liberals will argue (are already arguing) that it was deregulation and trickle-down economic policies that led us to this crisis. Fears of fiscal insolvency are overblown. Democrats should use their control of government and the economic crisis as a once-in-a-lifetime chance to make some overdue changes. Liberals will make a full-bore push for European-style economic policies.
On the other hand, the remaining moderates will argue that it was excess and debt that created this economic crisis. They will argue (are arguing) that it is perfectly legitimate to increase the deficit with stimulus programs during a recession, but that these programs need to be carefully targeted and should sunset as the crisis passes. The moderates will stress that the country still faces a ruinous insolvency crisis caused by entitlement burdens.
Brooks is saying that Democrats will have to decide whether the government is like the Marines or not? I hope they line up on the it's like the Marines side.
