Cdr Salamander found the below video. The differences between the reception of President Bush (a man that the left hates to this very day) and President Obama are striking.
Popularity is not an indicator of good leadership. School houses across the Marine Corps teach (or taught) that a leader should not seek to be "popular" with his men but should be fair, lead by example, emphasize mission accomplishment and stress accountability. It was said that if you were able to check those boxes that you would be a good leader/effective commander....but not necessarily popular.
Having said all that I've sensed the rising frustration within the ranks and have been predicting a recruiting/retention crisis for awhile now. The root of the issue is the "culture change" that the current President is pushing. I also believe that its part of the reason why Amos was held in such low regard. He was seen as an ally in the mission to fundamentally change the Corps.
Whatever the truth, read the whole story here.
SIDENOTE: When reading a Marine Corps Times article always check the byline. How it happened I don't know but they've employed several writers/reporters that have a societal change leaning to their writing and are more enthused about fashion, social trending news and gossip than they are about military matters....all with an extremely liberal view.
