If anything, Biden is being even more disastrous, and he’s as natural born as can be.
Trump is less so, his mom was British (a Scot) and his paternal grandparents were German.
It’s still a safeguard that remains in place (at least on paper) as it should. Biden may be a worse president than Obama, but using that as an argument for ignoring natural born citizenship is like arguing that a murder suspect with a long rap sheet shouldn’t be denied bail because the practice didn’t stop “John Doe”, who had no prior arrests, from killing someone.
