When to split

I’m working on a new column for Maximum Rocknroll about changing politics from one extreme to another; between one end of the Left or the Right, and between the Left and the Right. I’ve got my examples but I still need to explain the whys and wherefores. I’d intended the piece to cover both examples of individuals changing their politics and of social contexts that enhance or inhibit such political crossovers. Things are running long however and I’m committed to keeping all my columns to 1,500 words or under. So I might have to make this part one.
