MY answer is most of it... every thing below "Military service" read like a Tammy Duckworth campaign flyer with absolutely no balance or NPOV.   Now, The for starters, and one that defies logical argument is the simple question... How do you Swiftboat..see Swiftboating for details,  a real live war hero??? The implications are made with staining allegations and unverified speculations from bloggers and left leaning editorial commentators. No verified facts, just pure Ad Hominem attack with a good dose of  | Non Causa Pro Causa .
Finally, Why is there is nothing about the nasty Campaign flyers Friends for Duckworth have sent out on this or Roskam Article, again ..Why? See WP:SENSE and try to add that factual information, it will be removed off this article very quickly as Popol lovingly protects this article from any negative contributions.  Don't take my word or even believe me, look and see the entry logs and histories for your self.  

It is completely filled with glowing campaign flyer copy about her and bashing and negativity about Roskam.  It should be noted that  is a single purpose account, mostly editing on the Duckworth and Roskam Page.  Propol protectes the Duckworth page, and  dumps any thing negative and near slanderous entry on the Roskam article.  It is painfully clear what is happening and should be noted that most of the information on both article is not encyclopedic and conforming to WP:BLP and WP:NPOV Also,  is very smart and aggressive to use wikirulez to get his way.  See his histories and confirm, don't take my word for it.  Beware, to question means geting bad from those that protect this article
