In this Tuesday, Sept. 18, 2012 photo, Seth Lynn, right, director of the Center for Second Service at George Washington University, talks with Darren Phelps, a current student and former Marine, center, and Mark Kennedy, director of GWU Graduate School of Political Management, in Washington. Lynn, a Naval Academy graduate who spent six years in the Marines, says the "single biggest pitfall" veteran candidates face is overestimating the power of the war-service narrative. The "Candidate's Field Manual" developed for Veterans Campaign hammers that point home. (AP Photo/Ann Heisenfelt)
