Maryland? Maryland? Good luck with that.
As you are probably aware, the Northern VA jurisdictions started tightening up on illegals, so they went to the ‘sanctuary city’ locales nearby, i.e., DC and Montgomery/PG Counties in MD. So long as Marylanders keep electing what they do to office, you’re stuck with ‘em.
Prince William County has really tightened up, and illegals have self-deported. Probably to DC or MD, as you say.
