Baltimore native Nathaniel Fick appears to be in the audience at tonight's Democratic National Committee Convention session at Invesco Field in Denver.

Fick is the former Marine who authored the 2005 book, "One Bullet Away: The Making of a Marine Corps Officer." The recent HBO mini-series "Generation Kill" was based on his platoon's experiences during the 2003 invasion of Iraq.

He was once a registered Republican, and last year wrote about how a Democrat could get his vote. Apparently, Barack Obama got it.
