I know, right? This is quite a blow to those leftist bigwigs who were hoping to turn Republican areas blue by dumping illegal immigrants onto their streets, in the hopes that they'll go out & vote even though they're not supposed to. Which we know they do, by the tens of thousands and for the past two decades at minimum, and which the Democrats have increasingly not even bothered to pretend is a problem.
