Stop spreading misinformation. Being a convicted felon does not prevent someone from running for or being elected president. It’s specifically being involved with an insurrection, whether convicted or not, that disqualifies him from the office.

From the US Constitution:

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.
