That was a nuanced overview that hopefully people of all political stripes/locations could keep an open mind and learn from.
I'm not from the USA and the most interesting part that was new to me was the difference between Obama and Biden. Trump I was more aware of since it's in the news every day. Also I gained a better understanding of Sanctuary Cities.
From my perspective, it really seems like Obama handled immigration enforcement the best of the three. I think if Biden and Trumps terms were switched, then Biden probably could have continued the reasonable job (IMO) that Obama was doing, but since Biden followed Trump, there was more pressure and the pendulum swung to hard back in the other direction.
