Victor Davis Hanson, over at The National Review, is an accomplished classicist.  Today's column, "The Demagogic Style," was a short account of the early usage of 'demagogue' and 'demagoguery'  from Thucydides through Xenophon and Aristotle.  Once the apparatus is in place, Hanson turns to look at how the demagogic style works in President Obama's rhetoric.  One tactic that caught my eye was the strategic use of straw men:

3) The evocation of anonymous straw men, sometimes referred to as “some” or “they”

In the Manichean world of Barack Obama there are all sorts of such demons, mostly unnamed, who insist on extremist politics — while the president soberly and judiciously splits the difference between these fantasy poles. So for the last three years we have heard, but been offered few details, about the perils of both neo-con interventionists and reactionary isolationists, of both profligate big spenders and throw-grandma-over-the-cliff misers, of both socialist single-payer advocates and heartless laissez-faire insurers who shut emergency-room doors to the indigent in extremis — always with the wise Barack Obama plopping down in the middle, trying, for the sake of all the people, to hold onto the golden mean between these artificially constructed zealots.

Hanson's provided an interesting analysis of how demagogic moderates sell their ideas — they portray themselves as avoiding the vices of two extremes.  The trouble, as Hanson sees it, is that nobody actually occupies those extremes.  They are men of straw.

But a few things.  First, so far, all Hanson has done is say that the positions are anonymous.  That doesn't mean that they don't have occupants.  That just means that the president doesn't have to name his dialectical opponents.  That's an old rhetorical advantage presidents have always had — they are presidents. Second, Hanson's way off if given that President Obama doesn't name names, it means that nobody actually occupies that position.  I can name people on the two sides, at least for the medical insurance issue.  Mike Huckabee for the "personal responsibility" right, Michael Moore for the 'single payer' left.  Done.  Just takes some familiarity with the terrain, and we can easily populate those extremes for ourselves.

The straw man trouble with the setup, really, isn't that the extremes are anonymous or that they aren't populated, but that there is a lot of ground between the extremes.  And when one sets them that way, anyone can look like a moderate.
