In peace it's easy to lean liberal. In times of war our domestic population becomes infiltrated with returning veterans. The result: A more conservative generation with regard to family, politics, career choices, etc. As a veteran (Vietnam) myself I can relate to seeing and feeling the difference between who I was as I entered the Marines, and who I was when it was over. Veterans of war (my opinion) prefer more control and certainty in their civilian life as opposed to the chaos and uncertainty of the combat environment. This generation will produce trackable shifts in the Republican/Democratic balance.
