Should The Democrats Hold The Government Hostage?

If they ever want to actually increase taxes, then yes, according to Douthat:

This is the reality that liberals need to face: Much of the Republican “intransigence” and “hostage-taking” and “terrorism” that they deplore is a direct consequence of the fact that Republicans assume that Democrats will always, always, cave on taxes. And so long as that assumption keeps getting vindicated by events, there’s no incentive for the G.O.P. to accede to sweeping compromises on deficit reduction. Why would you compromise with a party that won’t actually fight for the revenues required to pay for the programs it claims to want to protect? Why would you sign off on tax increases that your notionally pro-government opposition doesn’t want to sign off on themselves? … In the long run, you can’t have compromise without intransigence.
