Whether or not natural born citizens are ever bad people is pointless as an argument.
When I was swearing in for citizenship, I still recall what the judge presiding the ceremony. Paraphrasing, what he said was that immigrant Americans are as good if not better than born Americans. I can reflect on my own contributions to the American economy, and lawfulness, and MAGA agenda. I would much rather a person similar to me run for president than Biden or Beto or Kamala Harris. Sadly I expect Kamala to be the first female & black president.
