as a former top level candidate associated with RNC politicians on a national scale, whatever sarahpac does is definitionally related republican messaging in general. to demonstrate otherwise, the republican party would have needed to disavow her actions at some point. palin is personally a republican strategist as a consequence of being deeply embedded in the very core of republican strategy! that's the entirety of her remaining political presence.
and where do you get the idea that being a 'DNC advisor' is something special? this means that the DNC hired her firm for campaign operations. do you mean to suggest she is on obama's campaign staff? i don't see any evidence of this
they're both just media talking-heads connected to campaign firms
