opinion, how quickly or how slowly it may change and of course starting with the phone in my hand, nothing today is as it was. no story, partisanship, it is all different. >> it is all different. and, so, basically we don't know how this is going to play out. we don't know what's going to happen to public opinion. my guess is that something has to happen in these -- in these hearings. there has to be a moment, probably, or a series of moments that clarify the allegations, the evidence, that really bring it home to people for there to be a sudden shift in public opinion. then again, it could be a gradual thing. it could be that the fact of these weeks of public testimony and people listening to them have a sort of an effective accretion on public opinion.
