Though it was a throwaway line and not part of any of the show's real storylines, the mention caused a political tempest today, with Tagg Romney going on Twitter to defend his dead grandfather. Slate has the full coverage of the Tweeting that ensued. All in all, I thought it was a fun reference to something modern in the shows' 60s context. And clearly a fun political tweak by the show's liberal creators as well.
