The Democrats know well that if they can get millions of people here in the US illegally somehow made into “citizens” - and dependent on Democrat largesse in what has become an endless list of government freebies at taxpayer expense - it will insure enough new Democrat voters to win every election for decades.
It’s nothing less than pure and unadulterated, in-your-face, political corruption, which the Democrats will never cede.
What’s astonishing is that there are Republicans who want this, also.
