Lowest Common Denominator Politics

In Mathematics, Common Denominator is a property of fractions.  So, if the term is applicable to humans, it is insofar as they are parts of a whole.  Thus, properly used, the "lowest common denominator" among any group of people is simply their Humankind.  Likewise, "lowest common denominator politics", properly speaking, is Cosmopolitics, i. e. the Politics of the whole of the species.  In contrast, what is usually intended by the term "lowest common denominator" in a social context, namely some characteristic that each member of a group possesses, is, more Mathematically properly, the "lowest common factor", and, likewise, politics in an Atomist society, such as the contemporary U. S., that pertains to commonality, is "lowest common factor politics".
