So far, the 2016 presidential campaign is not about anything very much, excepting issues specific to the leading and emerging candidates. It has been mostly about controversies swirling around Hillary Rodham Clinton, including the legacy question, which she shares with Jeb Bush. And more recently the focus has turned to the qualifications and electability of the emerging GOP newbies, from Sen. Ted Cruz, R-Texas, to Wisconsin Gov. Scott Walker to Sen. Rand Paul, R-Ky., who stand in the way of a possible third Bush presidency. In none of this do we see anything that speaks to the general state of the nation or mood of the electorate. At this point, 2016 seems more puzzling and less defined than other modern era non-incumbent races.
