You don't have to do deep investigative journalism to uncover the dirty truth that republicans has a smaller state as a policy goal, and has had it for a few decades. They say so publicly at any opportunity given. So, shockingly, when there's a deficit, they'll argue that the state should be smaller to cover the deficit. Sure, GWB massively expanded the state, and republicans were mostly fine with it, so it comes off as hypocritical. Either way, Bruce Bartlett just wastes a lot of words tracing and uncovering something that's trivially true.
Krugman dwells into conspiracy theory when he argues that republicans "enjoy" the deficit and with a nice slight of hand assigns the full responsibility for it to them. From random partisan hacks, sure, that how it goes, but for someone that likes to remind everyone that he has a nobel price, perhaps, just perhaps, we can expect a higher standard?
