It doesn't speak to apportionment however and there is precedent for not allotting it on the basis of non-citizens. So, you count illegals and add a question on the census form, "Are you a citizen of the United States?" You might add a second, "If not, are you in the country legally?"Yes. The 14th eliminates all slaves so there are no longer counts of 3/5 of a person. The 14th also requires a count of all persons. Unless you are arguing that non-citizens are not persons, you have no argument.
That is perfectly legal and has precedent too. You then have counted everyone, but when it comes time for apportioning money and seats, those here illegally don't count towards that. After all, they have no Right to representation in our government and are not entitled to use taxpayer funds.
