ALREADY SPOILED...
If you are like me who is an anime watcher, then you probably would have been puzzled that why did Saegusa Mayumi retire and how did *that person* become the Student President in the Yokohoma Disturbance Arc (Yokohama Souran-hen).
This Presidential Election Arc clears all those doubts. I was planning on skipping this arc, but I have grown to adore the characters of Mahouka Koukou no Rettousei, so thought of finishing it in a go. There isn't much to the plot as the anime watchers already know about the new Student Council Members. The chapters add more emphasis on the relationships of the characters which the anime is missing.
Decent artwork, lack of action, just a fun read!
