Dream or nightmare?

On Wednesday, I understand, Harry Reid will seek to invoke cloture for the purpose of passing the latest version of the so-called Dream Act. This legislation, which has never been debated in committee, would authorize the Department of Homeland Security to cancel the removal of, or adjust to lawful permanent resident status, any alien who can demonstrate that he or she: (1) has maintained continuous presence in the United States for five years and was not yet 16 years old upon initial entry, but is no older than 30 years of age; (2) is of “good moral character” and is not inadmissible or deportable on certain criminal grounds or as a risk to national security; (3) and has been admitted to an institution of higher education, has attained a high school diploma, or has obtained a GED in the United States.
This is amnesty legislation. The group NumbersUSA estimates that it would grant amnesty to an estimated 1.4 million illegal aliens between the ages of 5 and 19 and several million illegal aliens between the ages of 20 and 30 [see below for more precise estimates]. It would also grant amnesty to the family members of those illegal aliens [actually, there is no formal grant – see below]. Moreover, this is no one-time amnesty grant. According to NumbersUSA, the legislation has no time limit. As such, it would undoubtedly serve to attract many more illegal minors and their families.
No amnesty of this sort should be considered until the government demonstrates that it can control our borders. Will Senator McCain adopt this view, or will he vote for a free-standing mass amnesty bill?
UPDATE: According to an analysis by the Center for Immigration Studies of the March 2007 Current Population Survey (CPS) collected by the Census Bureau, an estimated 800,000 illegal immigrants under age 17 have been here long enough to qualify for legalization under the Dream Act. There are an estimated 900,000 parents of these illegal aliens. It is unclear under the Dream Act whether the government would deport these parents. It is also unclear what would happen to the siblings of legalized illegals who are themselves illegal, but do not meet the Act
