The Romney "welfare" ads are aimed at WHITE WOMEN [View all]
The Romney campaign found, through polling, that the ads were most effective with white women. The explanation for that (given on MSNBC last night by Jimmy Smith but I forget which program) is that the white women are the most concerned about families on the edge and the availability of benefits.
It doesn't matter to Romney if the ad is correct or lies. It is working with a critical target demographic. That's all that matters to them.
