It’s the Institutions, Stupid
Bobo’s fantasies about elites and bipartisanship notwithstanding, to the extent that the British system is “functional” where the American system isn’t, it’s because the Westminster system allows majorities to govern and the Madisonian system often does not. And I do think the former is preferable, understanding that you might get stuck with some idiot who thinks a return to Hoovernomics is a splendid idea and he’ll be able to implement his agenda to the delight of conservative American op-ed columnists and to the detriment of your own country.
