I would put the reason for listing as "too broad".
The trope definition is divided into 18 sections, two of which already have a page. One has a link to a related trope. Each section has a short description of various ways in how this trope is played out with each type having different uses of the trope. The description admits to the different types being used "depending on the story".
Now to the examples. Examples from the 16 sections without their own pages are scattered all over the long list, making it unnecessary difficult to find related examples of the same type of this trope. Examples of President Personable, President Scheming, and President Target are located right next to each other, the only thing they have in common is that they are fictional presidents.
Each type of fictional president should have their own page as they are tropeworthy. The main OPAD page should be made into an index or disambig.
