What if the plan is to get into a few months before the Nov. election, then Joe is found guilty of these crimes... and cannot hold public office by law? Dems only have 2-3 months to replace Biden with a new candidate, but too late to get anyone on the different state ballots?

Fourteenth Amendment Equal Protection and Other Rights:

Section 3 Disqualification from Holding Office:

No person shall be a Senator or Representative in Congress, or elector of President and Vice-President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability.
