Proper outlet for such a problem is 25 th amendment. That has to come from VP and a majority of Biden’s cabinet. If Biden contests it must go back and forth ( with time limitations) with both Houses of Congress. I believe 2/3rd from both Houses.
Let’s hope that they don’t. When Biden loses the election due to him being a complete failure, Trump will be able to walk in, and wipe out the scum that have tried to destroy our country. If someone else is put in place, the leftists might have some way of giving some pity party to try to beat Trump. But, the reality is, he needs to be the stooge to bring down the corrupt, anti-American, and in MANY cases, traitorous, DNC.
