I don't think Juliet really had that support last season that Cassadee had this season tbh. I mean, yeah, you saw here HERE a lot and some artist talked about her a lot, but I mean...I couldn't go a week without seeing "CASSADEE POPE, VOTE FOR HER!" at least 15-20 times by random people on twitter from Pete Wentz to All Time Low members, who tend to reach towards a bigger audience.
Plus Juliet was very much her own type of artist and not anything like the other two that have won, which I could see Cassadee falling into a cookie-cutter like the others. Oh wait, she already is there.
