Here is a rapidly developing scenario with complex threads that can stop the proceedings dead.
Candidate Donald Trump’s actions, words, and deeds have accumulated, painting a clear picture of his motive to gain power from the American political system by exploiting its weaknesses, undermining the rule of law, and attacking the US Constitutional form of government.
Supreme Court Justice Sonia Sotomayor, Associate Justice, warned that a candidate who has participated in an insurrection is illegal to run for office, making Donald Trump’s candidacy illegal from the start with due process.
18 U.S. Code § 2383 - Rebellion or Insurrection
Insurrection refers to acts of violence, but it's not the only charge that could apply. Seditious conspiracy, for example, is an effort to overthrow the United States government. People can be charged with sedition and conspiracy even if they never carry out the planned violence.
Rebellion or insurrection is a federal offense that criminalizes inciting, engaging in, or giving aid and comfort to any rebellion or insurrection against the authority of the United States or its laws.
While litigation against citizen Trump continues, with some halting to allow for his campaigning, that notion of “allowance” is inappropriate and underscored by his declaration of intent to make the office of president authoritarian, following the model of Hitler. His stated intention to use the federal military against citizens is more evidence. All that piles onto his apparent participation and leadership over the January 6 insurrection.
The Republican Party is responsible for failing to vet their candidate, making the party a co-conspirator. As such, the Republican Party’s non-profit status should be subject to revocation.
Corrupted by conflicts of interest, the US Supreme Court will receive rebuke and legislative attention for failing to uphold its ethics standards. One or more justices may be asked to resign and retire or risk prosecution, which could result in the loss of their retirement benefits. (This is Speculation, though a good idea.)
The Electoral College situation is a product of gerrymandering, which must be challenged, even if Kamala Harris wins the electoral vote. What if she does not?
If the Democrats lose the electoral vote but win the national popular vote, all the flaws in letting Trump become a candidate may be litigated.
Therein, the sleeper-sitting President, Joe Biden, will have a role to play by saying, “I am not leaving until this gets sorted.”
