Since politics itself covers a broad spectrum, there is no shortage of topics and sub-topics to choose from
Economy, political parties, military, laws, forms of gov't, health care, etc.
The possibilities are endless and because of it I'm having a hard time trying to categorize them. If I think of anything I'll let you know.
"Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passions, they cannot alter the state of facts and evidence." --John Adams
