It is not just illegal aliens. Legal, green-card-holding aliens vote illegally.
And more to the point, U.S. citizens with third-world origins, such as Hispanic Americans, vote overwhelmingly for left-wing politicians. Accordingly, every city, county, and state with enough such voters ends up lost to the GOP, permanently.
All immigration, legal or illegal, from the third world is poison. It will end our homeland.
The demographic time-bomb. It’s what they hope for and build towards relentlessly.
