Reagan didn't support open borders. Reagan said:
"A nation without borders is not a nation." Reagan did sign into law the Immigration Reform and Control Act of 1986. It specified prosecution and punishment for employers who hired illegals. If that law had been enforced over the years, the IRCA would have turned out to be what it was meant to be, a one time amnesty deal. Period. Instead, the feds lack of enforcement led to a series of liberal immigration policies under Bush41, Clinton and Bush43, and the main reason we have 10-15 million illegals living in the US today.
Btw, grow up.
