This may come as a shock to many people, but representation in Congress is based on total population, not on the number of citizens.
An influx of illegal immigrants changes the political map dramatically.
That is why “they” do not care if they are “legal” are not. Just bring them in.
Even if illegal immigrants cannot actually vote, they as a group, generally flood the already Democratic utopias (large U.S. cities) that already vote 80% + Democratic.
This gives those places more electoral college votes even if there are not more citizens.
This also gives those places more members of the House of Representatives (also taking those members away from other smaller (usually more conservative) states & towns.
This is the “fair” system that is being used against us.
Not enforcing the deportation of illegal foreigners has rigged the electoral college.
Founding fathers never thought laws would be cherry-picked to be or not be enforced.
This is why when you look at a voting patterns map of the United States county by county over the last two decades you see islands of blue surrounded by oceans of red.
