I do think it's possible to answer a simple question without being abusive, but since you started it you thick twat, there you go! Happy now?
Since it was entirely consistent with the Leagues's own internal rules, by which more clubs decided that Cambridge presented a better business case for membership than Barrow's, it looks like a decision the member clubs were perfectly entitled to make. So much for "crooked". I'd like to say I'm sorry to trump your emotion with reason, but I only deal in facts.
One thing the FL certainly did look at when considering applications for entry into the 92 was catchment area and/or whether the locals supported their hometown club. The author of one book I'd read suggested that the real reason clubs like Rochdale, Pools, Halifax and Crewe were never voted out was that the other club chairmen reckoned the aforementioned clubs had enough support as to warrant an FL team.
I think it's safe to say if this was still a thing, then the likes of Bwood and Harrogate wouldn't even get a single vote.
