The OP referenced, from the Hillary Clinton interview,
not only the 'this is abnormal' quote,
but Clinton's opinions on Bernie Sanders;
I have seen little in this thread
that takes those specific opinions into consideration.
So, this post will print out the part of the interview
in which Hillary Clinton speaks about Bernie Sanders.

In the doc[umentary], you're brutally honest on Sanders:
'He was in Congress for years.
He had one Senator support him.
Nobody likes him, nobody wants to work with him, he got nothing done.
He was a career politician.
It's all just baloney and I feel so bad that people got sucked into it.'
That assessment still hold?

Yes, it does.

If he gets the nomination,
will you endorse and campaign for him?

I'm not going to go there yet.
We're still in a very vigorous primary season.
I will say, however, that it's not only him,
it's the culture around him.
It's his leadership team. It's his prominent supporters.
It's his online Bernie Bro[ther]s and their relentless attacks
on lots of his competitors, particularly the women.
And I really hope people are paying attention to that
because it should be worrisome
that he has permitted this culture --
not only permitted, [he] seems to really be
very much supporting it.
And I don't think we want to go down that road again
where you campaign by insult and attack
and maybe you try to get some distance from it,
but you either don't know what y our campaign and supporters are doing
or you're just giving them a wink and
you want them to go after Kamala [Harris] or after Elizabeth [Warren].
I think that's a pattern that people should take into account
when they make their decisions.
Speaking of, he allegedly told Sen. Elizabeth Warren in 2018 that he didn't think a woman could win, a statement he vigorously denies.
How did you digest that?

Well, number one, I think [that sentiment] is untrue, which we should all say loudly.
I mean, I did get more votes both in the primary, by about 4 million,
and in the general election, by about 3 million.
I think that both the press and the public
have to really hold everybody running
accountable for what they say and what their campaign says and does.
That's particularly true with what's going on right now
with the Bernie campaign having gone after Elizabeth [Warren]
with a very personal attack on her.
Then this argument about whether or not, or when he did or didn't say,
that a woman couldn't be elected:
it's part of a pattern.
If it were a one-off, you might say, "OK, fine."
But he said I was unqualified.
I had a lot more experience than he did,
and got a lot more done than he had,
but that was his attack on me.
I just think people need to pay attention
because we want, hopefully, to elect
a president who's going to try to bring us together,
and not either turn a blind eye, or actually reward
the kind of insulting, attacking, demeaning, degrading behavior
that we've seen from this current administration.
