The thing that is being largely ignored up to now is that Trump is actually ineligible to run for POTUS under the 14th Amendment article 3. I think we are going to start hearing a lot more about this soon.
I'm the furthest thing from a legal scholar (thank feck for that), but does it really apply to Trump?
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.
As far as I can tell he wasn't any of those.
