Never. It's never happened...
Americans will not forget that Democrats aided and abetted rampant crime and law-breaking:
<><> nativist illegals cashing multiple govt checks using stolen SS numbers,
<><> nativist illegals falsifying govt documents to get US benefits,
<><> nativist illegals not paying taxes on all of their income,
<><> nativist illegals using stolen SS numbers,
<><> nativist illegals using faked driver's licenses,
<><> nativist illegals receiving payment(s) from foreign entities,
<><> nativist illegals receiving payments from tax-exempt latino groups,
<><> nativist illegals listed as lobbyists for latino pressure groups,
<><> nativist illegals filing multiple EITC refund forms,
<><> nativist illegals fasifying EITC apps listing non-existent children,
<><> nativist illegals w/ rap sheets here, or in a foreign land,
<><> nativist illegals who are members of violent reconquista groups,
<><> nativist illegals actively undermining US ntl security.
These are people who actually entertain notions of becoming legalized and getting on the pathway to citizenship. But they wonder aloud if it is even worth it.
As citizens, they would be required to pay taxes. As illegals, they can come and go as they please. But they complain that open borders drives down their wages as well. That makes them a lot smarter than your average open borders politician.
