It's possible that's for security reasons. If his challenges are successful, they will try to kill him. We've got a bunch of insane radical Marxist zealots who think that rigging the election and destroying the country are acceptable tactics if it means getting Trump out. It's not a stretch to believe they'd also see assassination as an acceptable tactic, if it ends all the legal challenges and Biden becomes the uncontested President.
An assassination attempt, much less success by a left-wing radical will not end with Biden in the White House. It would be an immediate Civil War, Do Not Pass Go and Collect 200 Dollars scenario. If the attempt fails, and Trump survives, you can expect him to immediately activate the Insurrection Act and as succinctly pointed out:
As an addendum, let me point out that in the first post I made on the matter, I specifically meant that if Trump invoked the Insurrection Act in the same words as the article uses as an example, it would grant each individual militiaman carte blanche to utilize his own judgement to take whatever means he deemed required to [eliminate the Democrat/Leftist government usurpation]. Given that this means Trump would be--without hyperbole--setting the Right-Wing Death Squads loose to kill anyone they damned well pleased if they thought it would help, any actual order Trump issues will probably be more clearly worded.
Let slip the dogs of war, indeed, the bloodshed would be immediate and
brutal. Imagine, if you will, 70+ million patriots, plus a sizable portion of the police and military being ordered directly to kill or capture every Democrat power broker and rabble rouser. The very agents that Governors and Senators rely on for their protection would immediately arrest or execute them. Government buildings would be overrun, politicians hung, shot or defenstrated. Community militias would roadblock major highways and gun down interlopers and government agents alike. Colleges and corporations would be stormed, and many agents of communist anti-Americanism executed by make-shift home grown Einsatzgruppen. The Democrat stronghold cities would
burn.
If the attempt succeeds, well....
If Trump is assassinated, and god forbid he is, there are three scenarios, none that are good.
1. President Pence takes over, but cannot stop rightwing violence. The right will take Trump's assassination as proof the left will never let them have peace, and you'll have massive uncoordinated slaughter like Rwanda and Yugoslavia, with different political groups instead of ethnicities.
2. President Pence manages to maintain some civil order, but only through draconian measures. Every politically active leftist will be doxxed and tracked, and 25% of the country will become the original definition of outlaw (someone who stands outside the protection of the law i.e. free game) in a de facto sense, possibly more given the growing resentment cops must feel. No DA protection is going to matter, because the DAs will mysteriously vanish. Any known leftist will be under constant threat of attack, and there will be literal scores of "lone-wolf rightwing extremists". Cops won't investigate these attacks. Their resources will be going to ensuring civil order. Leftwing political tactics won't work, and they had better keep their heads down. Crying victim, their favorite tactic, is only going to make things worse; tears make the best lubricant. Think cartoon-revisionist Dixie, where lynch mobs manifest every few hours.
3. President Pence doesn't even bother trying to keep order. After all, he's next in line. He unleashes the military to conduct mass arrests. There wil be massive concentration camps while people await trial (which may never come). They won't be executed per say; they're probably going to North Dakota or Eastern Montana or some other part of the northern great plains, and will either freeze or starve during the winter. Pence is going to assume full dictator powers under a Reichstag fire situation, and the future depends on if he's willing and able to give up power. Whether or not he is up to that decides whether America becomes an empire and he is our Caesar, or if we might have shot at staying a republic.
None of these scenarios end with Biden taking power, because with the current situation where a healthy majority of Americans see the election as fraudulent, the situation can only intensify the violence and aggression of the right-wing. Any Democrat taking power
after stealing the election and killing Trump will be seen as an unacceptable loss, and all high ranking Democrats will be priority targets for revenge killing at all levels from organization to lone wolves. Even in places where Democrats were legitimately elected, if such places exist, will be targeted as
any Democrat in office will be suspected of illegitimacy.
The only hope of Biden/Kamala
surviving after Trump is killed would be to immediately flee the USA and go into high security protective custody with an allied nation,
and even then they might get drone striked by an official order or by a particularly based drone pilot.
