Do Other Politicians Break Copyright Laws?

With Sharron Angle being sued for copyright infringement and Harry Reid posting full articles from the Las Vegas Sun, do other politicians have to worry about copyright laws. I've checked a few sites and the answer is probably no.
The closest to come to violating a copyright is Dina Titus. She posts a couple small paragraphs and provides a link. http://www.dinatitus.com/news
Joe Heck doesn't provide any news articles on his web site.
Rory Reid just provides links: http://www.roryreid.com/en/news_items
Brian Sandoval just has 1 story and it just provides a link: http://www.briansandoval.com/_blog/Brian's_Blog
Shelly Berkley has direct links to some news stories while also publishing a couple paragraphs in other stories: http://www.berkleyforcongress.com/in-the-press
Dean Heller puts in a paragraph of a story and provides a link. http://deanheller.com/blog/
Cathrine Cortez-Matso, Attorney General has news articles on her campaign web site but they don't say who wrote the articles. Was it a AG staff member or campaign worker? There is no author listed and it looks like something news bulletin from the AG's office: http://www.catherineforag.com/blog/
Stephen Horsford, Majority Leader of the NV Senate has a paragraph and links: http://www.stevenhorsford.com/index.php?option=com_content&task=blogcategory&id=3&Itemid=27
So, it looks like most politicians follow the coyright laws except Harry Reid and Sharron Angle.
