You will note a number of deeply nested <spans> because I'm trying to make it clear how metadata is related. Any thoughts?

You might try checking it against a distiller, such as here [1]

The generates the following turtle:

@base <http://www.examiner.com/tag/elections-2012> .
@prefix md: <http://www.w3.org/1999/xhtml/microdata#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix schema: <http://schema.org/> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

<> md:item [ a schema:CreativeWork;
     schema:accessRights "Do not distribute";
     schema:associatedMedia [ a schema:MediaObject;
       schema:audio [ a <http://schema.org/AudioObject >;
         schema:duration "PT1H20M04S"]],
       [ a schema:MediaObject;
       schema:name "Audio"];
     schema:contributor "Sally Pausin",
       [ a schema:Person;
       schema:birthDate "1965-06-22"^^xsd:date],
       [ a schema:Person;
       schema:birthPlace "La Jolla, CA"],
       [ a schema:Person;
       schema:affiliation [ a schema:Organization;
         schema:name "Professor, CUNY"]];
     schema:copyrightHolder [ a schema:Person;
       schema:name "Sally Pausin"];
     schema:dateCreated "2011-04-01"^^xsd:date;
     schema:encodingFormat "MP3";
     schema:keywords "Organizations";
     schema:name "The Early Years";
     schema:resourceIdentifier "HG6675";
     schema:url "http://www.x.com"] .

Looks like an issue with the contributor information, which should be a single item, not one for each attribute. It also looks like there's an extra space in an "AudioObject" property.
