http://weblogs.chicagotribune.com/news/politics/blog/2008/05/antimccain_ad_seems_to_work.htmlThe 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.
