Listen, that won't happen.
BO's ineligibility to hold office had to have been proven before or during his term.
It didn't happen.
To declare him a non-POTUS after the fact and then trying to undo all of the shit will create bigger problems, including a constitutional crisis.
That is why the didn't do it after Chester Arthur, our first despot POTUS.
Chester's father did not naturalize until years after he was born. it was a huge debate at the time. But his mother was a citizen so Chester had dual citizenship.
That is the precedent they used to get BO in office.
