As Governor of Alaska, she is the "Commander in Chief" of the troops she is seated with there. That was not a "Photo Op". That was the visit of a Military Commander with the troops under her command.
Good point. I would also note that Gov. Palin has a son who will soon be in Iraq; Sen McCain has on there now. With kids on the line, I trust their judgement to make decisons to deploy our troops more than Obama. To be fair, I do believe I read that Sen. Biden has a son in or on his way to Iraq. But given his repeated gaffes, and liberal politics, I’m not a fan...
They weren't under her command in the photo as they were in Kuwait. But they are Alaskans and a visit from your Governor is a big deal in-state or when deployed.
