Dramatic oversectioning 

It's not exactly vandalism, but the "micro-timeline" style you are trying to rewrite/revert the Cynthia McKinney article in is entirely inappropriate for WP biographies.  Please take a look at any bio for another congressperson (or in general, activist, politician, etc).  This sort of strictly date-oriented sectioning down to the sentence or short paragraph is simply not done; and it's not done with the very good reason that it reads extremely poorly.  In a more reasonable sized section (several paragraphs, at least), the prose describes the dates associated with the events/actions being described.

Actually, ther's quite a bit of purple prose (and partial sentences, awkward wordings, outright repetitions, etc) in the main text remaining... but reverting my efforts to clean it up is in extremely rude form.  Please don't do that! And don't add back so many headings... there are probably too many remaining even with my removals, but I'll probably make another pass or three at cleanup.
