One of the raft of primaries to be held on Tuesday 14th September is attracting particular attention. NY15 (New York's 15th Congressional District) is currently held by Charles Rangel - currently coming to the end of his 20th term. [he was first elected in 1970 - and is now over 80]. It is not his age which has made him vulnerable. The ethics charges which he is facing are the reason that this major player in US politics is facing a serious challenge.
There is a certain irony that the most most likely to topple him is the son of the long serving Congressman that Rangel himself toppled in a closely fought primary in 1970. Adam Clayton Powell was a prominent civil rights leader and pastor who was elected in 1944. A website about him can be accessed here. Rangel's main challenger on 14th is [Adam Clayton Powell IV] the son of Adam Clayton Powell by his third wife. [His half-brother, the son of Clayton Powell and his jazz (and classical) singer & pianist wife, Hazel Scott, is Adam Clayton Powell III].
Charlie Rangel's website can be accessed here and Adam Clayton Powell IV's here.
NY15 covers Harlam and northern Manhatten. In 2007 the district was 28% Black and 46% Hispanic - Powell is the son of the most famous black of his time, and the daughter of a mayor of San Juan, Puerto Rico - and was raised and educated in Puerto Rico after his parents separated.
