Alabama is right to exclude illegals from being counted for apportioning Congressional seats
Democrats have been using illegals to unconstitutionally gain House seats. That is why they are so weird about a census question on immigration status. It is also why Democrats unethically facilitate illegal immigration in hopes of gaining even more seats illegally. In amendments to the constitution after the Civil War, it was made clear that apportioning was to be based on citizenship. At this point, it is just one more of many constitutional provisions the Democrats find inconvenient to their objectives. The fight over the census citizenship question seems to have been just one skirmish in a larger war over who deserves to be part of America's democracy.
