at least for me. Until now, I've never read of any real testing of political ads. (h/t TPM Campaign Wire)

Anti-McCain ad seems to work

The Democratic National Commitee ad that attacks Sen. John McCain for his 100-years-in-Iraq remark seemed to have the desired effect with some of the all-important voters who see it, making those voters look less favorably on the senator from Arizona.

That's one conclusion to draw from a study of how some voters reacted to the DNC ad that edited snippets of McCain with video of violence in Iraq.

HCD Reseach Inc., a market research company, found that independent voters went from 50 pecent who saw McCain in a "mostly favorable" light before they saw the ad, to 40 percent after they viewed the ad.
