I had a very scary thought last night about the time between now and Jan 20. What if KH invokes the 25th Amend to get FJB out so she can be installed, then she selects someone to replace her as VP AND Pres of the Senate, and that person refuses to certify the results.
Please correct me if I'm wrong.
I did some research when they were discussing using it a few months ago. What I learned is that using the 25th amendment is by design a slow and time-consuming process. Not enough time to use it between now and Jan 20.
The founding fathers again were prescient in making the process difficult so it would not be used for "light and transient" reasons.
