Create a fuLL-page ad with a list of every single Obama promise made during the campaign, and in the next column how he betrayed his promises (or denied saying it)and the public trusr.
TRANSPARENCY-NEGOTIATIONS ON C-SPAN-NO NEW TAXES FOR HEALTH CARE-PUBLIC OPTION-ROLE OF LOBBYISTS-DEFECIT-EARMARKS and so on.
Of course I would follow-up with TV-internet ads with his exact words.
YES HE CAMPAIGNED ON CHANGE-BUT WHAT WE HAVE IS CHANGE FOR THE WORSE
