To the extent that McCarthy even has an argument, it seems to be that Congress shouldn’t think about doing anything else until the supply chain is fixed. But mostly he’s just railing against using “infrastructure as a Trojan horse to push radical policies.” Which ones are those? Child care provisions that would strengthen the economy by helping more mothers seek paid work? Climate provisions that would both decrease the likelihood of future “natural” disasters and strengthen U.S. infrastructure to be able to absorb the stresses of extreme weather so that it isn’t as disruptive? McCarthy also takes time to decry “anti-competitive tax increases on small businesses and families” that no one is even trying to pass, unless the families he means are the likes of Bezos, Walton, and Gates.

Anyway, for those who care about reality (not really the audience he was looking for), McCarthy left himself open on a couple of fronts, and Psaki hammered them:

So, 1.) the economy is improving from where it was when Donald Trump was in the White House, thankyouverymuch. And 2.) Dude, supply chains need infrastructure. Democrats are trying to pass infrastructure. Republicans are blocking the way.

Again, it’s sort of pointless to try to pick apart what McCarthy is arguing in this letter because coherence or consistency is not the point. The point is being seen to always oppose everything Democrats do, and to convince people who aren’t paying much attention that what Democrats are doing is exacerbating supply chain problems without even beginning to sketch out a theory of how that is true. He’s taking two big complicated things—the global supply chain and Democratic efforts to pass hard infrastructure and social infrastructure bills—and trying to mash them up together without explanation, or even the acknowledgement that the Democratic legislation he’s fussing about has yet to pass.
