Rep. Linda Sanchez recently spoke out against laws like the new Arizona immigration law, saying (report here, audio here):

"There's a concerted effort behind promoting these kinds of laws on a state-by-state basis by people who have ties to white supremacy groups.. It's been documented. It's not mainstream politics."

Obviously, in her mind effective immigration enforcement isn't "mainstream", despite the fact that the great majority of Americans (i.e., the mainstream) support it. But, it gets worse:

...Sanchez told the newspaper after her speech that she based her accusation on online stories, particularly a blog written by Andrea Nill, an immigration researcher for ThinkProgress, an offshoot of the liberal Center for American Progress Action Fund.

Nill wrote that the Immigration Law Reform Institute, the legal arm of the Federation for American Immigration Reform (FAIR), helped write the law. The Southern Poverty Law Center has labeled FAIR a hate group, a designation that the organization disputes.

The groups that Sanchez considers credible sources are in fact not very credible at all. Please refer to the dozens of posts at the following links to find out just how little credence one should give to the opinions of those listed:

* Southern Poverty Law Center
* Center for American Progress
* Andrea Nill
