Among establishment Republicans (also known as cuckservatives, who never really supported Trump), a lot. In the real world, way less than the Clinton collapse hurt Clinton.
Between September 12 and September 13 in the LAT/USC poll, Clinton dropped a full 1.6 points, and Trump rose by 1.7 points. Between October 8 and October 9 in the LAT/USC poll, Trump dropped less than half that -a mere .6 points. I suspect Her rise (only .3 points) was muted by the wikileaking of the emails.
America already knew Trump was rude ten years ago. Evidence Trump was rude eleven years ago isn’t going to change that.
