I will point this out...if you take the number of non-Americans in the country at 22-million (often suggested), and figure that three-quarters of this group are in California, NY, and Florida (my humble guess), then the question weighs greatly upon the 2024 Presidential election and the Electoral College.
You can figure lesser populations counted, and the three states combined would lose at least nine Electoral votes, and those nine votes likely shift to red states (mostly southern states).
This would also reshape a significant number of states and the district-drawing scheme, and put the Supreme Court into a full-time job of trying to figure ‘fair’ district drawings, or not.
I will point out that 22 million illegal aliens equals the entire population of Nevada, New Mexico, Nebraska, West Virginia Idaho, Hawaii, Maine, New Hampshire, Rhode Island, Montana, Delaware, South Dakota, Alaska, North Dakota, DC, Vermont, and Wyoming.
Don't forget Texas, Arizona, Georgia, the Carolinas. etc..
This cuts both ways and isn't as straightforward as it seems. The immigrant population is pretty widely dispersed.
