I kinda' understand your point. otoh, the decisons made by our represenatives effect all of us living here, citizen and non-citizen alike. I would presume that initially, and I'm only guessing because I/we live in a vastly different world from the founders, they thought that reresentation of ALL living in the district was important enough to count - or - perhaps it was just a compromise for southern slave owners.. I dunno.
On that, if you'll indulge me an anecdote:
I live in Tennessee's Fifth Congressional District, inside the city limits of Nashville. I've been here over a quarter century. when I first arrived the 5th district was centered over Nashville and extended into the nearby suburbs. My representative was Jim Cooper (D). I came to TN a registered Republican. Jim had an office in downtown Nashville and was always accomodating when I asked to speak with him (when he was not in DC) and his staff always opened the door. He (or a staff person) always answered my correspondence, even where we disagreed. I could tell it was read because the answer usually addressed specifics in my correspondence. I became supportive because I felt represented, even though we disagreed on some items.
Flash forward to now, the TN State legislature gerrymandered the 5th district after the 2020 census. They split Nashville into thirds and extended three districts through the city, beyond the suburbs and the 5th now extends south of Columbia. The R's got their desired result and a
George Santos clone Republican was elected in the 5th. If he has an office, I don't know where it is. He lives somewhere between Columbia and Hohenwald almost 100 miles away. he, nor his staff has ever, not once responded when I wrote, utilizing the email submission form on the US Congress website. He doesn't represent, in any way, whether we agree or disagree on issues.
I tend to think a representaive Government should represent everyone living within the jurisdictions.
