I can't speak for Rand Paul, but I have no doubt that many of the politicians pushing amnesty for illegals know exactly what's going on, and either approve of the transformation of the US Southwest into an annex of Mexico (or, to be more exact, a dumping ground for Mexico's surplus population), or simply don't care. It's more important for the GOP to bend over backwards and prove to the establishment that they aren't "nativist" or "racist."
They are not representing the people and their ancestors who built and created those civilizations.
they are sworn to protect and defend the Constitution to God. They will have to answer to Him for that.
Amnesty is not Constitutional. If they believe the Constitution is racist and they don’t want to follow it for that reason, then they can appeal for an amendment.
But this mob rule business paves a dangerous path for the future.
