select a.*  county a, cd b a.state = 'virginia' , b.state = 'virginia' , b.cd114fp = '06' , st_contains(b.geom, a.geom)

this docs geodjango queries. https://docs.djangoproject.com/en/1.11/ref/contrib/gis/geoquerysets/

geo = serialize('geojson', county.objects.filter(         state="virginia"         geom__intersects=cd.objects.filter(state="virginia", name="06")       ))
