Mitt Romney dismissed 47% of the voting public in 2012 and was roundly criticized for dismissing the people he supposedly wanted to lead.
If Clinton had said 46%, would that have made it ok?
It's not dismissing them, it's saying they hold contemptible views. Just as, at one point in time, I'd imagine 50% of the population were in favour of slavery.
It's not a good political move, but it's telling the truth.
I don't have any problem with what Clinton said. Based on the numerous polls, she is absolutely correct. It may not be a politically prudent thing to say, but that's not an ethical matter.
Which is fair. It's impossible to deny that there are white supremacists (who are deplorable) that support Trump. They're very candid about it.
So what is the acceptable number? "Almost half"?
And what does that say about the rest of the group? Are they too to be damned by association, for standing too close to the "real deplorables"?
Apparently the apology was over "half" rather than "deplorables".
