My goodness... let's not start arguing about May and Misty.... In the words of Misty from the first movie, "That's a fight that nobody's going to win." >_<
Anyway, I voted for: Misty, May, Sabrina, Blaine, and Wattson. They're my favorites, nothing much else to say... um, Brock and Morty were close seconds. Misty and May probably would be at the top of my list, because they are almost equal in my mind as my favorites, and the other three are just my favorite gym leaders. ^-^
But, yeah, this poll could really be split into "Favorite Trainer" and "Favorite Gym Leader". Ah well, it doesn't really bother me.
