^x4 I don't think they would rig the elections itself (while I wouldn't be surprised if they did, i think this is the only thing they don't touch lol), but I definitely think they at the very least, heavily influenced the venue choices.
As mentioned above, It's SKE's 10th anniversary alongside the 10th SSK elections, and Jurina is a clear contender for 1st place. So in the event that she does win the crown, doing it at SKE's home ground of Nagoya dome would be amazing for her. SKE fans would have pushed it regardless, but I still think management played a part in deciding the venue. After all, the fan chosen venue thing was only to cover their own backs in the event of something going wrong like last year's disaster. JP fans on 2ch and the like commented on this from way before the whole "fan's can choose the venue" thing came about, so literally no one was surprised at the venue being Nagoya Dome.
