Absolutely not, since it's an obvious power grab for the sole political benefit of the Democratic party. And DC already has enough power and influence.
There's a pretty obvious difference between "DC" in the federal agency sense (many employees of which do not live in DC!) and the 600K+ people who live here who, with the exception of one (1) vote every four years have absolutely no influence over federal policy.
Also the idea of delineating who does and doesn't deserve federal representation because of the pre-existing mount of influence they currently have seems... very problematic.
Yeah, we should also arbitrarily reduce the California's number of Representatives and electoral votes by 79.38% as they already have way too much influence, or maybe it's because they vote D
