Tho most Presidents are trained as Senators , Governors and Generals , they were first graduates of college, almost all of them. If you can count West Point then even more so.
Some Presidents ,like Reagan, went to less famous schools and lots of congressmen are graduates of less famous schools , but my point is that the big old schools are over represented.
Can we hold this academy responsible for some of the present situation? for good and for ill?
