The final piece of the puzzle is the band Exciting which can be found at the TV station in the other town accessed vis the subway. Once you have them enslaved and they have done their campaign, you should then be able to enslave the secretary and carry out the election.
Just one thing to note, the dev has had issues with over corruption of characters that lead to dead ends, because you have passed a trigger point before it was available. If you find that even after you have enslaved the band and had the campaign speech, that those options do not show still, I would advise using AON's Better Experience mod to lower campaign rating to 60%. This is what you should have as it is 10% for each campaign speech. (Church, School, Police, Hospital, Ex Mayor's family and Entertainers.)
