Nope. You've got it about as wrong as possible. The first use of a
name in an article should be first and last name, and after that, the
last name only is used unless it would cause confusion. AP publishes a
style book that most newspapers follow at least
loosely. Some follow it more closely than others. Political
afilliation is not used unless it impacts the story in some meaningful
way. Spitzer didn't do any of the things he allegedly did because he
is a member of any particular political party, organization, race, or
religion. All are incidental to the story, so none are prominent in
the stories. They mention that he is married, and has children because
that DOES help tell the story.
How does getting arrested for tapping your toes while taking a crap in an
airport bathroom warrant having your political party affiliation mentioned
two or three times in each paragraph when the story is reported?
You might be right. Show me an article in which that happened. If it really
happened, there's a 100% chance that I'll agree with you.
