I ride regularly with veterans from the Korean War, Vietnam the Gulf War and more. They vary in ages from the early 70s to their 20s. Universally, they do not like this president. It goes beyond that. They absolutely loathe him for what he has done to this country and to the military.
It has been my experience that discussions with them leave me with the same conclusion.
It has also been my experience in those discussions that, even with the negatives Bush deserved for his stance on bi-partisanship, No Child Left Behind, Immigration and such, he still maintained a high degree of respect and approval from veterans and military personnel.
I think it is because they knew that his respect for those in uniform was genuine, not some cocked-up stance to present an appearance or win political points as often appears to be the approach of the current occupant of the White House.
If he even bothers to go that far. They are fortunate when it is just detached contempt they see...that would be preferable to his military-despising meddling in both operational and budgetary aspects.
