"In other words, you know, this question of whether a former president is disqualified for insurrection to be president again is, you know, just say it, it sounds awfully national to me. So whatever means there are to enforce it would suggest that they have to be federal, national means. Why does -- you know, if you weren't from Colorado and you were from Wisconsin or you were from Michigan and it really -- you know, what the Michigan secretary of state did is going to make the difference between, you know, whether Candidate A is elected or Candidate B is elected, I mean, that seems quite extraordinary, doesn't it?... Why should a single state have the ability to make this determination not only for their own citizens but for the rest of the nation?"
Said Justice Elena Kagan in today's oral argument in Trump v. Anderson (transcript here).
Kagan's question was reinforced by Justice Ketanji Brown Jackson: "Can I just ask you about... the concern about uniformity and the lack thereof if states are permitted to enforce Section 3 in presidential elections.... I guess my question is why the Framers would have designed a system that would -- could result in interim disuniformity in this way where we have elections pending and different states suddenly saying you're eligible, you're not, on the basis of this kind of thing?"
