“The man can only ride you when your back is bent, so strengthen it so America won’t get taken for a ride.”
That’s the passage that all the Greek Chorus Liners cite when trying to tarnish her speech.
Yet it is not hard to understand or incoherent.
But I just looked it up, and apparently Palin was referring to this quote from Martin Luther King:
"Change does not roll in on the wheels of inevitability, but comes through continuous struggle. And so we must straighten our backs and work for our freedom. A man can't ride you unless your back is bent."
