Per the media blurb, Deal leads among "younger voters" (undefined) 45-35, but Carter leads among 40-64 year olds 50-36. That sounds inverted (though IIRC this is at least the second straight poll showing Perdue with a lead among young voters). If it was somewhat inverted, that would play to Deal's advantage considering the relative share of the electorate each age group makes up.
In the past when I would see anomalies like this, I would think it couldn't be right. Weirdly, though, there's a consistency in Georgia in both pre-election polling and exit polling for the younger folk to be (slightly) more Republican than older ones. I think it may have something to do with growing up in an era with few credible Democratic candidates statewide. In 2008 for instance, Georgia was one of like three states where 18-29 year-olds went for McCain (51-48). The 30-44 group was close to 55% Obama; his best performance, age-wise. Jim Martin won 18-29 year-olds in that election, though.
In fact, when you look at exit polling by age, there's not a whole lot of difference by age in GA; here, it always comes down to race.
