I am trying to understand this sentence from this video on youtube ('U S Funds Iran Nuclear Program.CNN News report' - it is around 4 min 17 seconds in the video).
'When I suggested there was a change of policy, I didn't for a moment go into some sort of polyanna lapse that assumed that anyone at the Bush administration would be intelligent or sensitive enough to think about a change, but Congressman Dingle, Congressman (name not clear) showing some considerable presence, and frankly, some forward looking consideration ..are they demanding they change?'
I looked up the meaning of 'polyanna' and it means
1.an excessively or blindly optimistic person.
adjective 2.(often lowercase) Also, Pol·ly·an·na·ish. unreasonably or illogically optimistic: some pollyanna notions about world peace.
Does the above sentence (in quotes) mean that the speaker (Lou Dobbs) is saying that he was not (making the mistake of - because he used the word 'lapse') being excessively optimistic in assuming that the Bush administration would be sensitive enough to change?
It may be difficult to understand the meaning without the proper context such as a background on what the Bush administration did, or how the speaker (Lou Dobbs) views this topic.
