The Rev. Jim Jones (left) was an integral part of the Democratic Party political machinery in the San Francisco Bay Area. Through him and other ministers, especially in the African American communities, the party was able to construct an impregnable culture in the region based upon Marxist ideology. Political figures include the late San Francisco Mayor George Moscone, Congresswoman Nancy Peolsi, former SF Mayor Willie Brown and U.S. Senator Diane Feinstein.
