Surely you can't be that stupid, so I have to conclude that you're being ridiculously disingenuous.
It seems to me that you're the disingenuous one. You believe obviously that in those kind of meetings Clinton conspires with the wealthy donors present to dupe the people into voting her and then enforce policies that reward the latter. And you're just frustrated because there isn't a way for that incriminating stuff to come out and help your candidate.
Alas, the truth is much more mundane. I suggest you read Game Change. It contains an interesting anecdote about a 2008 fundraiser with Bill Clinton at the aftermath of Ted Kennedy's endorsement of Obama.
You started this discussion by citing two recent Presidential candidates who got rightfully blasted for making deeply offensive remarks at their fundraisers. Neither you nor I know if Hillary is saying stuff like that too, but you certainly can't exclude the possibility.
So you are curious to know if Hillary called Appalachian whites "rednecks" or if she called Ted Cruz an "asshole".
Me, I have more serious thing to agonize over.
It's pretty important to know what a presidential candidate truly thinks of the people she's running to represent.
One of the saddest and most disturbing things about the Sanders campaign and their supporters is the way they start from a place of utter distrust and assume the worst intentions in everyone, and then demand that their opponent be held to absurdly high standards in order to prove a negative, to prove that the Sanders campaign's dastardly insinuations are not justified. So most people are ok assuming that Clinton is having normal strategy conversations with her donors at these meetings, just like every presidential candidate ever. The Sanders people start from the assumption that she's selling out the American people or revealing "what she really thinks", which would obviously be something horrible and campaign-ending, and then now it seems like y'all not only want to demand that she allow them to be recorded, but are saying that it's the patriotic duty of every American to do so and that's how the political process should work.
And the most irritating part is that you only do it on issues where the divide works against Clinton, like here where Sanders doesn't have meetings because he
doesn't have friends doesn't have any big donors. We could just as easily make these disingenuous assumptions about Sanders' behavior and force him to do something degrading or prostate himself to prove that he's not actually a nefarious evildoer, but we don't.
