@MusiqueNow firstly, it's possible because the Democratic Party botched the election by nominating such an obviously flawed candidate. Harris should have never been the nominee.
Ok, so now what? First, let's never forgive the Party for their screw up. They need to be held accountable.
But what can be done now? There actually is something: 14th Amendment time. NOW is the time for Congress to judge whether Trump is eligible based on the insurrection clause.
The earlier efforts failed in court because that wasn't the right venue. It never was.
But THIS IS.
...not that enough of the country is aware of how this works, so the handle won't be pulled.
