Simply put, the idea that Democrats are for open borders while Republicans are for closed borders is a myth borne out of ignorance and tribalistic non-thinking. Democrats are opposed to Trump, not immigration regulations. Democrats are in favor of strict, highly regulated, massively expensive immigration policies just like Republicans. The Democrats do this while attempting to sound less xenophobic, but their policies are very similar. This is politics, not ethics, and we would do well to not be so naive.
