Trump told us the 25th would come back on Biden. We’ve had many hints. My theory is that Biden has been intentionally misled into decisions for this moment to take him out.
The derps used him for their next move. You see the media turning against Biden? This was all planned. Who will replace him? We will find out soon enough.
I'm no legal expert but this is how I understand the process. If they follow the 25th amendment it would be K.Harris that would replace him; Harris would then select a VP and Congress would have to approve.
If they oust K.Harris prior to her becoming President, as in the Nixon/Agnew/Ford scenario, then all bets are off as to who it would be.
