Here are a couple of articles I found very interesting.
First one is about Mitt Romney, and his increasing elusiveness the longer he runs for president (pushing five years now). http://firstread.msnbc.msn.com/_news/2011/10/07/8208708-the-relatively-unknown-mitt-romney.
The second one is about the importance of endorsements when choosing the GOP nominee. Records show that endorsements had a bigger impact than money or name recognition. http://fivethirtyeight.blogs.nytimes.com/2011/09/23/romney-leads-endorsement-race/.
