Any polls from "We Ask America" should be discounted:

(To be clear, I just found this article. I didn't do the research in the "UPDATE.")

UPDATE: So I did some research on the identity of We Ask America. Its website only discloses that it is a division of "Xpress Professional Services, Inc." But it does not tell the reader what exactly that means, which turns out to be quite significant.

Xpress Professional Services, Inc. is a subsidiary of the Illinois Manufacturer's Association, which is an anti-union, anti-tax, and anti-Health Care Reform industry advocacy organization.

Its CEO is Greg Baise, who was a 1990 Republican candidate for Treasurer, losing to Pat Quinn by 11%. He is also Treasurer of the Economic Freedom Alliance, which has targeted Democrat Bill Foster with advertising labeling him as a "job killer" for his support of card check legislation.

The bottom line is that this is a partisan Republican pollster and an arm of the pro-business Illinois Manufacturer's Association. There is nothing wrong with being a Republican pollster or being an arm of the Illinois Manufacturer's Association. However, there is something wrong with the half-ass disclosure on the website of an affiliation with "Xpress Professional Services, Inc.," which could be anything, instead of a full disclosure of the direct link to the Illinois Manufacturer's Association and its Republican principals.
