What we’re seeing is Trump running down a Kubrickian hallway that just leads him right back to where he started. It’s delicious. 
If it were just one trial or set of charges he was facing, it might succeed, but the sheer plurality has his resources strained to the point of breaking like a computer forced to compute too many complex equations and thereby slowed to a crawl, left defenseless.
Let me know when we get universal healthcare, the federally protected right to abortion, equal pay across race and gender, federally protected rights for lgbtq folks, federal legalization for cannabis, and all the other things progressives have been demanding for decades…
It may require that Trump first be convicted in at least one of these cases before such a challenge could actually proceed in court— or that a judge would have the guts to hear it.
In recent days, there’s been rising discussion of how the Constitution should, in theory, block Trump from being eligible to run for president again. Multiple legal scholars have pointed out that the 14th Amendment bars people from running who have violated an oath of office previously, “either through overt insurrection or by giving aid or comfort to the Constitution’s enemies.” Notably, the Constitution does not require a formal court conviction on insurrection charges.
By any reasonable measure, of course, this applies to Trump. Even if he insulated himself from direct communication with people convicted of sedition, it’s indisputable that he gave aid and comfort, and continues to do so by championing them and promising them pardons. But, of course, the law is not a button you push that automatically turns the clear language on paper into enforcement in real life. Without a mechanism to enforce the law or the political will to enact it, Trump is coasting straight towards a spot on a ballot he should, by law, be barred from having.
