Martin Wolf at The Financial Times:

The fact that Trump is lying is not news. What is news is that, even shorn of public office, Trump defines the truth for his party. There is a word for a political organisation in which the prime duty of members is absolute loyalty to a leader who defines what is true and right: Führerprinzip (“leadership principle”). The Republicans’ wholesale embrace of Trump’s Big Lie is a perfect instance of it. This, alas, is far from all. Trump’s Big Lie is being weaponised through state legislation designed to subvert elections. Much attention is being paid to obstacles to voting. But death threats have also hounded honest officials out of office.
