It's not exactly false though. Half the people that now suck his dick on the regular trashed him in 2016. Everyone assumed he was going to lose, and then he won, and they dived right into full on sycophant mode. Why? Because Trump winning was the mark that the majority of the "Republican Base" was no longer controlled by Republicans, it had shifted and grown into the MAGA nation. Trump took their voters, and they were terrified that he could turn it against them at any time and force them to lose their primary. It's always been optics.
Why are they still supporting him in this coup attempt? While I agree some of them probably are hoping it succeeds, I feel the vast majority simply understand that just because Trump isn't going to be President anymore, does not mean he won't keep his grip on the base. They are always going to be terrified of what his sweaty little hands can do to them when he decides to press that Twitter button. They are hoping that silence or vague "He has every right to challenge stuff." will keep them off the radar.
That isn't even getting into the fear of it all. The Republicans created this rabid base, and Trump full on weaponized them. Hell,
this is even what the PA Senate Majority Leader said recently in regards to PA Republicans attempting to stop certification.
They raised, nurtured, and trained the leopard and then let a madman take it from them and teach it to love eating faces.
Could the Supreme Court do something unprecedented and overturn the election? Yes, but the chances are so astronomically low. Not only would it set a huge precedent allowing states to sue over all types of "state" issues from legalization to voter suppression to clean air laws, all of which would be plunged to the SCROTUS, but it would basically destroy the bench as installing an autocrat means the checks and balances will become worthless. They have incredible job security, so it's unlikely they would give that up for anyone, let alone Trump.
