What was Ging trying to accomplish at the election of the 13th Chairman? It seemed that he had a plan and that everything went according to it, excepting the part where Pariston resigned from his position of Chairman. What was his full plan and what was he truly trying to accomplish (his final target)? Did he really wanted Pariston to be the 13th Chairman or his plan had a continuation?
From Ging's actions I like to think he wanted to have some fun. He just wanted to manipulate people into doing something he had already predicted. Like Pariston he didn't have his eyes on the presidential seat. His interactions with Cheadle, Leorio etc. seem to be always aimed towards creating chaos.
I think this line sums up his motivations in the 12th election
