Ossoff is not hiding. He is highly visible everywhere.
It is Handel that is hiding. And, of course, real issues are hiding.
The Handel campaign is looking only for Republicans in its ads.
Ossoff is clearly looking for independents with the assumption that Democrats in the district are eager to wear the independent label.
I agree with your analysis that “He’s not one of us” is absolutely crazy. About as silly as “Stronger Together” and the other nonsense Hillary slogans.
