The biggest problem with the analogy, though, is procedural. Krugman imagines the Republicans as some jerk who has no right to bother anybody. In reality, they are elected lawmakers, part of a coequal branch of government. They hold a majority in one house of Congress and a large enough minority in the other house to frustrate the will of the majority under its rules. What they are doing is, strictly speaking, entirely legitimate, even if it can be reasonably seen as reckless and obnoxious. (The same was true of the Democratic majorities that enacted ObamaCare in 2009-10.)
To Krugman — and, apparently, to most Obama-supporting Democrats, there’s no such thing as legitimate opposition.
I see. The Republicans opposing Obamacare are the same as the Democrats who passed it.
I suppose there’s not much difference between the different factions of the Ruling Party after all.
