I’m not sure where you get that margin from. This would be enabling legislation of a constitutional amendment. It’s amazing that the author has the mendacity to treat this as serious. It can’t get a majority in the house, and I’ll bet not even the never trumpers vote for it in the senate. No way it gets 60 votes
It required a 2/3rds majority in both chambers.
Please read the last sentence of Section 3.
Section 3
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.
