The real test?

When? He is right, it is about change and who you stand up for
or what you fight for.

When?
When will he stand up to those that manage his campaign?
When will he fight those that stand by him in his campaign?
That is the test. NOW!(no pun intended)
When will he face his own flip-flop or lack of nuance?

If he cannot and Obama has already(to a great degree) not cast labels upon the
water, then I don't know if it will be "Katy bar the door" but he should be left behind.

He has yet to finish his speech and his is quite a story, which was dramatically and theatrically introduced.

[As far as prepared for "them" and how it works, his speech so far, and maybe his world if populated by "straw" men and red herring.]

[...formally and neutrally known as Digression, he has concluded his very inspiring speech, which is my segue to his story, about a fundamental change that took place in Hanoi, which should indicate that his change already took place, so there may be little hope for a change now.]

[Meanwhile, I won't hold my breath.]
