Pro-immigration reform group America's Voice is going after CNN host Lou Dobbs in a big way, and it's using Facebook's targeted advertising to do so, ClickZ reported.

America's Voice targeted Capitol Hill staffers, CNN employees and employees of other media companies with anti-Dobbs ads, including one with Dobbs' picture that reads, "Hey, Anderson Cooper, what's it like to work with a racist at CNN?" according to ClickZ, which added that the group considers Dobbs to be an anti-immigrant hatemonger.

The group is also running display advertising on liberal and Latino blogs such as Firedoglake and Latina Lista, and Blue State Digital is handling the paid-search component of the campaign, ClickZ reported.

America's Voice director of online communications Jackie Mahendra told ClickZ:

All of the advertising so far has been digital, and whatever we raise will go to traditional media. In this case, we were looking to really deliver a message to media professionals, specifically at CNN and other networks. We very inexpensively saturated the space for Hill staffers so they were able to see the ad an average of about 50 times.
