Former Arkansas Governor Mike Huckabee's contribution may merit more attention than most. Huckabee is fast becoming the joker in the Republican pack, with the polls suggesting he is a serious contender.
But it is difficult to imagine any Presidential candidate - including, probably, Bush in 2000, having less experience or interest in foreign policy.
Huckabee's worldview is somewhat all over the place. But most striking is the opening in which he sounds like Obama on foreign policy and how America should lead in the world if it wants others to follow.
"The United States, as the world's only superpower, is less vulnerable to military defeat. But it is more vulnerable to the animosity of other countries. Much like a top high school student, if it is modest about its abilities and achievements, if it is generous in helping others, it is loved. But if it attempts to dominate others, it is despised.
The Bush administration's arrogant bunker mentality has been counterproductive at home and abroad".
He writes too of wanting to "treat Saudi Arabia like we treat Sweden" and makes energy independence a priority.
The article has evoked criticism from Republican rivals for using the Democrats' playbook and talking points.
Yet Huckabee's evident talent has been for empathy for the public mood. Whether his quirky campaign maintains its momentum remains to be seen. But the changes needed to restore respect for America may be becoming a bipartisan theme.
