Here is a good recent example:
http://en.wikipedia.org/wiki/Lori_Robinson
A lot of very good men were passed over to give this University of New Hampshire grad this lofty position. Many of them actually attended the Air Force Academy. They spent their lives preparing for such an opportunity as she was given.
Also, please note the BROOKINGS INSTITUTION. This is just a very liberal garbage political think tank. It has noting to do with preparing her to be a general.
She’s not even a pilot, nav, WSO. . .she rides in the back and worked a computer. . .yup, just the type you want to lead Air COMBAT Command where training and experience at the leading edge and making decisions defined if you lived or died.
She is a putz.
