Where did the addresses come from?

The addresses came from a Private investigator. This investigator worked previously with democratic disaster and a few of our volunteers. He got them from different databasis. The whole point is to verify the address and see which properties does he own or owned under the name Stanley ann dunham, Kelly ann Dunham, Shirley ann dunham, Anna Toot, Madelyn Dunham, Stanley Armor Dunham, Ann Sutoro, Ann Soetoro, Ann Obama, S. Ann Obama.
Smbd stated that many addresses are properties rented by campaign. I don't believe campaign would rent properties under the name of the candidate.
