This site is nearly moribund, especially when compared to active SEs. The number of questions that gets asked and answered every day is well below the number that would be necessary for a thriving stack.
A large part of the problem is that there is not a sizable community involved in the site, and the focus of the site actually harms the effort to develop a community. People have raised issues of accepting literature questions to increase readership and including policy questions, and I believe that those are adequate, but not long term solutions to the problem. The majority of political boards get around this problem by allowing speculation, pontification and opinion based responses but that is neither desirable nor really possible here.
Is a potential solution to try to focus more explicitly on Political Science rather than the quotidian questions of politics, writ large?
