I think most Americans know next to nothing about how immigration works in the US.

As much as I hate Biden's moves on asylum and immigration, the sad fact is that these moves are broadly popular with the electorate in both parties.

As someone said recently, the electorate loves the idea of a strong border. But they don't really like to see what that means in practice.

It is why you get such mixed polling on immigrants and border policy. They are broadly ignorant about the issue.
