Rove was against the NRCC TV ads from what I hear. The house hired their own professional consultants to develop the ads. Those consultants should refund their consulting fees.
It is NOT in the interest of corporate America to support any mean-spiritedness. It is in their best interest to allow the free market to rule with no labeling of workers as "illegal". It is also in their interest for immigration to separate out terrorists, welfare parasites and truly bad people from the ordinary workers.
It is in corporate interests, however, to continue to have access to a "disposable" worker pool....effective border management interferes with that goal. Effective anti-illegal immigration politics , from that perspective, is contrary to their interests. The best way to derail an anti-illegal immigration politician is to label him anti-immigrant.(or, for that matter, an anti-illegal immigration party)
