Strict Constructionists would deem the illegals as lawbreakers and send them home or require the Federal Government to do its job and protect our country. You sir are making a nonsensical argument.
No that is simply a Failure of the Executive Branch over the last 50 years to enforce current immigration laws.
And a Strict Constructionist should have the intelligence to understand the the words "Persons" and "Citizens" are two different things and have different definitions.
Thus, is the Framers had only wanted us to count citizens, they would have stated that in the Constitution.
