Whether or not the language is in the bill is irrelevant. If a social service is offered to the general public, the government is prohibited from excluding "persons" from taking advantage of it.
Even if the Jackass party allows the such an amendment, it is just one SCOTUS ruling away from providing healthcare to all illegals.
In the late 1970s, the State of Texas enacted legislation that denied a public school education to the children of illegal immigrants and denied state aid to municipalities that attempted to educate those children. Many illegal immigrants filed suit and all of the cases made their way to the Supreme Court. In a landmark ruling, that most lawyers know about, and that every professor of constitutional law knows about, called Plyler vs. Doe (1982), the Court ordered Texas to make the same education available to illegal immigrants as it does to citizens.
In so doing, the Court held that:
(a) the Constitution protects “persons” ; and
(b) “persons” are citizens as well as strangers, people born here and people who end up here, people here lawfully and people here unlawfully; and
(c) in the area of social services, whatever benefits the government makes available to the general public cannot be kept away from a class of persons based on their immigration status or that of their parents.
In other words, the U.S. government cannot give “free” health care to citizens without also giving the same free health care to illegal aliens, without violating the Constitution.
Hussein's legal credentials are impressive. He cannot say, with a straight face or under oath, that he knows nothing about this SCOTUS ruling. The fact is that he knows it, and his advisers know it. They'll add the anti-illegal provision, knowing full well that it will be struck down by the SCOTUS in the future, thereby providing de facto free medical care to all illegal aliens.
