Probably because Romney and his cult are a bunch of cowards who haven't served in generations, missing WW I, WW II, Korea, Vietnam,and more.
I think even the Kenyan in the WH has a brother in law who served, but these Kolobians are way too special to put on a uniform.
You can’t seem to be able to differentiate between someone who hasn’t served, but is patriotic (Romney) vs. someone who actively hates the military and the US and all it stands for (Obama).
