To his admirers and supporters, President Trump is something of a political Superman, not only for what they see as his miraculous feats but also for his seeming imperviousness to injury, even those wounds caused by his own words and deeds. He survives or even prospers from things that would kill any mere mortal politician.But even the Superman on television during my childhood had one vulnerability: the fictitious mineral known as Kryptonite, which would rob him of his powers. Trump’s Kryptonite is a familiar political foe by now: inflation.
