I get what you say about the TV telling low-info voters of what to believe, but Phil Robertson has never engaged in giving any sort of political advice on the show. Furthermore, you insult many "Duck Dynasty" fans on this board, by linking their enjoyment of the show with those of a low-information voter. DD fans are generally conservative, and numerous studies have shown that conservatives are more politically aware of the issues, and are likely to obtain their information from a wider variety of sources (sans the MSM).
It’s a fictional show. You may as well be defending professional wrestling. I’m sure pro rassling fans are just as conservative.
