I'd give the story a little longer to spread; only 58% have heard of it so far. Democrats, independents and HRC all say that (in net) it makes them less likely to vote for him, for whatever that's worth, but the effect appears to be quite small. Post-Trump politics, eh?)
Um, where did you see that? The tweet says that 80% of non-Trump voters say it doesn't make any difference to them.
In the poll, 58% of respondents say they've heard of it
I'm referring to the second part of your post.
Check the crosstabs
Clinton voters 4% more likely/8% less likely
Democratic 7% more likely/13% less likely
Not gonna lie, it would be very surprising to me if respondents said that they were *more* likely to vote for a candidate after a sex scandal. Also, I think the margins you just listed would be more aptly described as more or less a wash than a net hit to Cunningham's margin.
