It's interesting (and logical) that Glinda would be conceived as being supporting, but, seeing the show pre-Tonys, Chenoweth made so much more of an impact than Menzel that they both seemed like leads. Glinda opens and closes the show, and she goes through a much larger change over the course of the show than Elphaba (also, Glinda's arc is better dramatized IMO). And Chenoweth was really, really hilarious. I saw the show again post-Tonys, and I thought Menzel had really come into her own, while Chenoweth was much more schtick-y than she had been. But the first time, it was all about Kristin.
I've always thought that Menzel was lucky that Chenoweth decided to leave the show a month after the Tonys, and that was announced during the voting period. If Chenoweth hadn't been leaving, I think Chenoweth would have gotten some of Menzel's votes and Menzel might not have won.
