Alton Towers knew Nemesis would win when they held that competition. They’re not fools; they know which of their rides is still the most popular.
I'm sorry but that's b'locks. In terms of how many people go on it, Nemesis is currently the third most popular ride in the park at best.
I doubt they expected so many obsessives to register probably hundreds of votes each before they announced the poll.
I'm not pursuing my point about the name though, as I wrote the order of words in the sentence slightly wrong and you're probably correct on the decision being made beforehand.
