Here's an ad attacking Thom Tillis for his alleged stance on health insurance reform.
It's paid for by Patriot Majority USA, a DC-based advocacy group that doesn't want to tell you much about itself but seems closely tied to Democratic leadership and union funding. Complaining about opaque, out-of-state organizations pumping money into this campaign is going to be like complaining about the weather, which is to say common, legit, and useless.
The ad is deemed by people who follow such as things as, essentially, true enough (credit WRAL with a reasonable caveat for the months ahead: "It's hard to imagine any 30-second attack ad on health care getting a clean bill of health.")
As for effectiveness, it does an OK job of reminding North Carolinians that Kay Hagan's presumptive opponent (and, really, any GOP nominee) will either be against the stuff that people unabashedly like about the ACA, or have some not-very-convincing plan to repeal it and fund the popular parts only. This commercial is not as polished as the rival AFP spots, and I'd guess it's not supposed to be. While the anti-Hagan ads carry a dual message -- "Obamacare failed, and, we really do care about reg folks like you" -- this one has a single, blunt point to make.
I'd like to see some Obamacare messages voiced in a more positive way. Show me a guy from Rocky Mount who has coverage despite a pre-existing condition, and a woman from Pineville who was able to leave her job and start a company of her own. Let's hear from some of the surprisingly-large number of North Carolinians who have signed up for coverage in our exchange-free state. Less happy stories work, too -- say, from individuals and institutions hurt by the failure to expand Medicaid -- but those still would be grounded in the intended benefits of the ACA.
Attack ads seem to be effective, so I don't expect them to go away. But I prefer a positive message, and I think it's important for Hagan to stake a claim to the good things she helped bring about.
