Worth noting that Oden ranked 22 in the midpoll. Be interesting to see how all the Wano characters roll out.
Did they get their hits on on Kaidou before the poll ended? That might have affected things.
That's a weird argument to make when said popular character is being pushed in a specific way that makes the majority of the fandom believe they'll be the next Strawhat. So of course they'll rank higher than everyone else, including much older characters.
Jinbe did terrible his first time around, and even after he was obviously going to be a strawhat he made 35, The most recent he did 6th but he's surely not going to do anywhere near that well again.
Plus Carrot is certainly getting NN push and has been for years, and at least in the midpoll, didn't do as well. Still 17 which is absolutely solid but not any particular push.
Chopper has always been 4th or 7th, Robin always 12 or under, Nami always 8th or under… Luffy, Zoro, Sanji in the top 5...
Franky has never done better than 13, Brook has been 19 the last two times... just being a strawhat, or strawhat candidate, doesn't ensure a spot.
Then you have Law who placed 10 his first time around and then 2nd... while Ace and Sabo have both been consistently been top 10, and Hancock 10 twice. (Japanese readers LOVE Luffy, so his brothers do well... and rather than hating Hancock for her being in love with him... they EMPATHISE with her. Weird, but seems to be the case.)
Obviously as the crew got to be about 10 members it became near impossible for all of them to rank in the top 10, or even the top 20, but even official strawhat-ness doesn't guarantee a high spot, let alone potential.
