Many originalists do not "reconcile" with the AR 15. I think it's obvious from the text & context that the 2d Amendment included the notion of "regulation" ("A well-regulated militia"). The 2d A. as incorporated by the 14th A. is an individual right, but it is not an insanely absolute right.

Another read is not that SCOTUS is shy about confronting Trump but that they're basically on board with his project but would be embarrassed about the legal arguments they'd have to make if they upheld his actions on the merits, so they find procedural means to let him get his way.

10/ When Trump asserts that the President "represents" the Federal Government and thus has special powers beyond the Constitution's text or original meaning - and even contradicted by it - he is just building on Roberts's conveniently pro-presidentialist assumptions and unsupportable logic.

9/ Roberts: * "Only the President (along with the VP) is elected by the entire Nation" * “directly accountable” through “regular elections” * the “most democratic and politically accountable officer in Govt.” Remarkably, he published this within a week of a decision about the Electoral College.

4/ The Help America Vote Act created the Election Assistance Commission to certify digital systems, but not a power to abolish mail-in voting. I don't know of a statute that offers even a plausible legal argument for the president or any exec agency to abolish or substantially curtail mail-in votes
Jed H. Shugerman (@jedshug.bsky.social) reply parent
3/ The Constitution gives the states this fundamental power over elections, and Congress is the back-up. Congress passed HAVA, the Help America Vote Act, in 2002 to help states replace the infamous punch-card ballots that were a disaster in Florida 2000. It promoted mail-in voting as an alternative.

Jed H. Shugerman (@jedshug.bsky.social)
Trump just posted that he would issue an executive order to ban mail-in voting. Bottom line: He cannot. Neither the Constitution nor any congressional statute gives the president such an executive power. He followed up with this whopper, extreme even for Trump's past views of presidential power:

My draft article goes into depth on the key statutory term "alien enemies." It had a widely understood legal meaning in 1798. Tren de Aragua members do not fit that meaning, even though the group is a designated "Foreign Terrorist Organization."
Andrew Kent (@andrewkent.bsky.social) reposted reply parent
On "invasion" and "predatory incursion": in 1798, those terms in the Alien Enemies Act clearly had a war-military meaning--an attack on US territory. The Trump administration's interpretation is incorrect. I may have used a sledgehammer to kill a gnat, but it seemed important . . . .

5. (out of 5): I replied, "Thank you for acknowledging that Netanyahu caused this hunger crisis by decided to cut aid, to serve Smotrich's and Ben-Gvir's plans to starve Gaza, then ethnically cleanse and re-occupy Gaza. I think I'll leave it at that."

4) So even though I couldn't imagine the Roberts Court ruling against birthright rule before, I can now - after a month of utter nonsense rulings. And wouldn't the Trump admin read tea leaves as a green light for more reckless defiance of the rule of law, to mix metaphors (green tea leaves)?

Trump DOJ would come back and say "Loyalty" or "Invasion" is a relevant legal question, and this group does not have sufficient commonality for what we argue is a relevant legal question, which is also a fact-intensive case-by-case question. Tell me why I'm wrong to worry about that.

6/ I'm less worried by what Sauer listed, and I'm more worried about made-up distinctions like "allegiance," "loyalty"... or if this or that group constituted an "invasion" (see Judge Ho's new made-up distinction).. and any other "creative"/"clever" nonsense distinctions might block a class.
