Coup attempts: After attempting to steal the election by accusing his enemies of stealing the election, and after committing sedition in front of everyone and inciting a violent insurrection, Trump shouldn’t have been allowed to run again. The Supreme Court got it wrong in their 5-4 decision that was billed, somehow, as a 9-0 decision. Before that decision landed, I shared my opinion in Is Section 3 of the 14th Amendment Undemocratic?.
Constitutional monarchy: I enjoyed this article, which suggests that the US should become a constitutional monarchy and invite Beyoncé to literally be Queen.
Electoral system: Proportional representation. The US should transition to a German-style proportionate representation multi-party parliamentary system.
