under state law, presidential candidates need to qualify with 500 signatures from each of indiana's nine congressional districts. indiana elections officials say that in st. joseph county, which is the 2nd congressional district, the obama campaign qualified with 534 signatures; clinton's camp had 704. but the signatures, which were certified by the elections board, were never challenged. if the number of legitimate signatures for obama or clinton had been challenged and had fallen below the legal requirement of 500, they could have been removed from the state ballot. reports have previously put the number of phony signatures for both candidates at about 150, but state investigators plucked names from the petitions at random and cited only 20 individual alleged forgeries as part of their case.
