Politics is a dirty business and I'm in the mood to see one female political figure finding out that for her, it will be very dirty and eventful when she meets her match.
1) She can be Governor of a state or Mayor of a city with clean reputation
2) He can be a Senator or member of city council that she never sides with on issues for the state or city
3) One discretion from her past is discovered by him or he could stage an incident to frame her
4) He confronts her, makes his demands and she agrees to pay him off
Unfortunately for her, he makes a recording of her offer and confession that can then be used against her. Now that he has her, she's his and his life just became easier politically while she has an unwilling sex life with him that she could eventually grow to love or constantly dislike yet keeps coming back for more and more.
