Kudos to ABC for actually doing the story, but it's just incredible how ingrained these narratives are in the brains of our press.
I've done my best to never try to make assumptions about the political views of "the troops." They aren't a monolithic group, they all signed up for a variety of reasons, and they have differing personal circumstances. Still to anyone with a moderate bit of intelligent it shouldn't be all that surprising that some of them might not be thrilled about their extended trip to the desert and might not be thrilled to support candidates who want to make it an even more extended trip.
