When?
I've never heard of him going.
I always see pols going to see the dead as a bullshit thing to publically do. It's never impressed me. B/c they don't go unless there are cameras.
I had a shipmate get killed. They buried him where his family had lived for his whole life, not even the mayor bothered.
So it's bullshit for him, Bush, etc to go, unless they go sans cameras and media.
Sorry to hear about your shipmate. I've lost several myself. Never saw any politicians at the services.
While I'm not so cynical as to believe any person sitting as President and Commander in Chief would use dead heroes as a jumping board for political reasons, I'm realistic enough to know that if they do attend, their "handlers"/PR folks will want to put it on display. In addition, the Press Corps, which follows politicians around like dogs following a truckload of Liver Snaps hoping for a big story, also want to view anything attended by a politician. Did you notice the uproar by the Press when they were denied being able to go to Dover AFB?
The CiC has been to Dover before. This is from October 2009.
