60 second ads are generally a bad choice short of Presidential politics or a high profile, statewide race. Why? Voters just don't care that much.
That alone makes Burners ad a tough sell. Clearly, her campaign understands that "Darcy Burner, know it all youngster" wasn't ultimately the best image of have ingrained in people's minds. The results of 2006 showed that.
This ad is an admirable effort at course correction (sans George W. Bush no less!). But, it throws an awful lot of information at the voter and let's be honest, even with an attempted image makeover, she still looks awfully young - which the "I worked for safe toys!" testimonial does little to correct.
Best news for Republicans: serious 60 second ad buys burn through cash pretty quickly.
