issues of first impression
??? Examples please. I ask, because I agree that this term of art probably can be correctly applied to the question of whether the 14th Amendment can be used to disqualify candidates from a Political Party's primary ballot, However in other respects , I am not convinced the expression "issues of first impression" correctly applies. Trump would not be the first person to be disqualified under the 14 Amendment. There is quite a history there, but not recent. In the past, The disqualification clause was, in an indeterminable number of cases self-executing.
You seem unaware that the U.S. House of Representatives spent months, and possibly millions, on a detailed investigation of Jan 6th. Their product was a comprehensive report upon which both the Department of Justice and the lower Colorado court heavily relied. Any suggestion that Donald Trump has not been determined to have engaged in insurrection by any formal process is spurious. Nothing could be further from the truth.
I questioned, in my own mind, from the outset Colorado's authority to dictate to political parties which candidates can be on their primary ballots. (That same issue, at least not precisely, does not arise in the case of the State provided Ballots for a National election.) There are nuances here. Regardless, no reasonable person could fault the Colorado S.C. for reasoning that if Trump has disqualified himself then it does not make sense that his name would be on the Republican primary ballot; yet I question the authority of the Colorado S.C. to dictate to a political party what names can be on their Party ballots.
The S.C. can read just as you and I can. I think they prefer to punt but will have a difficult time figuring the best way to do it. My best guess is that they may focus on the Colorado Republican Party primary ballot issue and rule rather narrowly. It's possible, for example, the S.C. could rule that Colorado may not keep Trump off the Party's Primary Ballot, leaving the question of his qualification for the National ballot in the Fall for the future.
We can read. The Court can read. It will be just as difficult for the S.C., as it is for any well informed American citizen, to conclude that Trump is qualified,
under the Constitution, to run for the Office of President. He took an oath AND he's a proven insurrectionist whose goal was to overturn the results of a National election and illegally seize the Office of President; thus thwarting the transfer of power as required by our Constitution. It's a straight forward issue for all but Donald Trump and for lawyers who make little money when an issue is easily settled. Lawyers therefore, out of necessity, must surely hone their ability to read selectively and especially to misread, sometimes to the point of embarrassment*, whenever a case threatens to be too easily resolved.
