Freeper debate cannot undo the law unless they persuade Congress to change it.
Note that the first 9 presidents of the US were born outside US jurisdiction, because the US did not exist. They were born on US soil and qualify only from the clause “citizens at time of Constitution adoption”. Their parents were most certainly not citizens of the US and they were born outside US jurisdiction but qualified via the relevant clause.
I know there is some desire to outlaw illegal immigrants’ babies from citizenship via birthright, and God knows why since those people are nearly all devout South and Central American Catholics, anti abortion and would not vote Dem, but for some reason that’s the attitude.
But none of that matters. Jurisdiction is the key word. If you want it undone, you will have to pass laws, and that’s not going to happen.
There’s also the matter of grandfathering where people born before any such laws are enacted will have a case to be exempt from some new definition. That means the 2060 election would be the first one where the exclusions sought by some could actually go into effect. IMO its a stupid fight to take up and those who push for it open themselves up to attacks of being racist.
