The 1986 amnesty was Ted Kennedy's idea, and strictly enforcing existing immigration laws from then forward, promised by the Simpson-Mazzoli Act, was supposed to be part of the deal. So Reagan (who later said it was the biggest mistake he made) and Congress (Dems and Repubs alike) went along and gave amnesty to almost 3 million illegal aliens, sending the message, that if you can steal in and stay long enough, the Americans will reward your illegal acts by giving you amnesty. How strong was that message? We now have 4 times as many, or more, wanting amnesty.
So, let's give these 12 million illegals amnesty and in another 20-25 years it will be 48 million wanting amnesty. Does that sound like a good idea?
