What it will do to Hillary is cost her Pub and some Ind votes.
Any Republicans voting for Hillary this year surely already thought of the people who nominated Donald Trump as deplorable.
It plays against her unifier message. She divides the people into the deplorables and the others and who knows, maybe the others are further subdivided into categories.
Pubs voting for her will pause after this and take a second look of her and the Donald and a large number of them, particularly the more educated ones will choose the Donald over her as the lesser evil.
It’s the same thing which cost Orman his election. He spoke his heart and was exposed for the partisan Democrat hack that he was.
Did Orman have a gaffe like this?
While I think this was a mistake, especially given how the media is spinning it, I don't think it's quite the same when you're talking national electorate vs Kansas statewide electorate--the latter is far more conservative as a whole.
