Hot take: Courts might be able to review the legality of this impeachment, even under current political-question doctrine. Here’s why and how the issue might arise:

Suppose Senate convicts and disqualifies Trump from ever holding federal office. Trump files paperwork to run anyway, but state officials deny his application, citing his Senate impeachment judgment. Trump sues, arguing that the judgment is void.
Normally a legal dispute about a prospective candidates eligibility to run would certainly present a justiciable case or controversy. But are courts bound to accept the Senate impeachment judgment as valid? Maybe not. Here’s why:
According to Article I, “The Senate shall have the sole Power to try all Impeachments.” This is a small amount of judicial power vested in Congress. When trying impeachments, the Senate sits as a court.
The Senate’s judicial power includes the power to decide relevant legal questions that arise, such as what procedures are sufficient to constitute a “trial” w/in the Constitution’s meaning. Such legal determinations are conclusive, as SCOTUS held in Nixon v. United States (1993).
The constitutionally required procedures and what offenses constitute impeachable “high crimes and misdemeanors” are impeachment “merits” questions, so to speak. The Senate has the “sole” power to decide such questions. But *who* may be impeached is arguably different.
*Who* may be impeached and tried by the Senate is arguably a question of the Senate’s impeachment “subject-matter jurisdiction.” Without such jurisdiction, the Senate has no power at all to try. The resulting purported impeachment judgment would be void, just as would a court’s.
Imagine that the House purported to impeach an indisputably private citizen that never served as a federal official for federal crimes, and the Senate purported to try and convict them.
I’m fairly confident that we’d all agree that the Senate’s judgment would be completely void, and a court could certainly recognize this invalidity in some sort of collateral proceeding presenting the issue of the judgment’s validity.
So if we consider the who-may-be-impeached question as a matter of the Senate’s subject-matter jurisdiction to try impeachments, then later courts can likely review that question when it arises in disputes about the purported impeachment judgement’s collateral legal consequences.
A court’s subject-matter jurisdiction can pretty much always be challenged in a subsequent collateral proceeding that turns on the validity of the prior court’s judgment. This is an ancient and basic rule of judicial power. A purported judgment rendered w/o jurisdiction is void.
Senate impeachment judgments should be no different, because the Senate sits as a court when trying impeachments, exercising *judicial* power. So it all comes down to whether to consider the *who* question an issue of the Senate’s impeachment jurisdiction.
Nixon v. US presumes that the Senate has the power to try, which makes its factual and legal determinations conclusive. But if the Senate doesn’t even have the power to try in the first place—because it lacks jurisdiction over the defendant—then its “sole power” doesn’t apply.
So while I agree with @steve_vladeck, @WilliamBaude, and others that Trump indeed *can* be lawfully impeached and tried, I disagree that courts cannot answer that legal question when it arises in a normal case or controversy.
(And perhaps the more precise label for the *who* question is *personal* jurisdiction, rather than subject-matter jurisdiction, but that label doesn’t affect justiciability because either way it’s a jurisdictional question.)

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.

The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.

The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.

Once upon a time there was a Raja named Uttānapāda born of Svayambhuva Manu,1st man on earth.He had 2 beautiful wives - Suniti & Suruchi & two sons were born of them Dhruva & Uttama respectively.
#talesofkrishna https://t.co/E85MTPkF9W


Now Suniti was the daughter of a tribal chief while Suruchi was the daughter of a rich king. Hence Suruchi was always favored the most by Raja while Suniti was ignored. But while Suniti was gentle & kind hearted by nature Suruchi was venomous inside.
#KrishnaLeela


The story is of a time when ideally the eldest son of the king becomes the heir to the throne. Hence the sinhasan of the Raja belonged to Dhruva.This is why Suruchi who was the 2nd wife nourished poison in her heart for Dhruva as she knew her son will never get the throne.


One day when Dhruva was just 5 years old he went on to sit on his father's lap. Suruchi, the jealous queen, got enraged and shoved him away from Raja as she never wanted Raja to shower Dhruva with his fatherly affection.


Dhruva protested questioning his step mother "why can't i sit on my own father's lap?" A furious Suruchi berated him saying "only God can allow him that privilege. Go ask him"
