Krugman discusses the Cardiff Garcia article here. It divides demand-siders into "fiscalists" and "monetarists". Monetarists is tricky because that already has significance for a theoretical perspective, but I like the term "fiscalists" because it would really help to clarify a lot of sloppy discussion of what Keynesianism is if the policy view is just given a different term. Of course most Keynesians are probably fiscalists (some might not be - for example, John Taylor), but if you had a separate term for a normative, policy perspective people could be more clear about how they use the word "Keynesian".
Krugman goes through his own policy thinking on the relationship between monetary and fiscal policy, but that's mostly old hat. I think everyone gets that except for Scott Sumner acolytes, and I honestly can't imagine they've actually missed that - they just need something to whine about so they say Krugman doesn't think monetary policy makes sense at the ZLB.
