This article is a long read but it's a good one. It basicly breaks down how those that used lies to push Welfare Reform are using the same ones for Immigration Reform.
Fols wonder why Bush was able to lie so easily about WMDs that didn't exist? Well, the formula and strategy has been used before on other issues. Issues that many claimed were "A slam dunk".

"Many persons who have spoken and written in favor of restriction of immigration, have laid great stress upon the evils to society arising from immigration. They have claimed that disease, pauperism, crime and vice have been greatly increased through the incoming of the immigrants. Perhaps no other phase of the question has aroused so keen feeling, and yet perhaps on no other phase of the question has there been so little accurate information."
By Doug Brugge
These words, written in 1912 by Jeremiah Jenks and W. Jett Lauck, who had been part of the United States Immigration Commission, sound surprisingly contemporary. In 1995, there is a popular argument that immigrants are responsible for many, if not all, of the problems facing our country. This theme has been struck before in US history. It has arisen now in part because right-wing organizations have promoted immigrants as a group targeted for blame. For example, an organization prominent in this right-wing campaign, the American Immigration Control Foundation (AICF), in a 1992 mailing, lists immigrants as the culprits behind high taxes, wasted welfare dollars, lost jobs, high costs for education, and rising crime. AICF claims that immigrants are driving up health care costs by grabbing free care while also bringing disease into the US. Interestingly, subsequent versions of the same letter, sent out the following year, reduce their claim of 13 million illegal immigrants to 6-8 million, a number still higher than that cited by Time magazine as no more than 5 million. As Jenks and Lauck conclude in the above quote, the debate is still characterized more by angry talk than by facts.
An important ingredient in the success of the right's anti-immigrant campaign is its ability to deflect anger about the negative effects of the current US "economic restructuring" onto the scapegoat of immigrants. This tactic nests within a larger goal of capturing political gain by exploiting a popular issue. This is nothing new, but rather is a practice rooted in a long-standing history of reaction to immigration, nurtured today by a cluster of right-wing political organizations dedicated to this single issue.
The History of US Immigration
It is impossible to understand the current wave of anti-immigrant sentiment without some historical perspective. Indeed, excepting the Native American population, it is often said that the US is a nation of immigrants. Certainly, the role of cheap immigrant labor has been critical in building the US economy. Immigration has been both voluntary and forced. In early US history, territorial and economic expansion was a magnet for persons fleeing poverty and political repression. There was also forced immigration in the form of the slave trade and the annexation of one half of Mexico by the Treaty of Guadeloupe Hidalgo, signed in 1848, at the end of the Mexican-American War. This, not traditional immigration, is the reason that a significant number of Chicanos in the Southwest live in the US rather than in Mexico.
