Just came across this over at PPP. They just released a poll, taken entirely post-conventions showing Hillary Clinton up by 5 points. Most important, however, her favorability increased by 9 points from a net -15 a month ago to just -6 (45/51). This is the best rating I’ve seen for Hillary in months, and hopefully, a precursor of things to come. Meanwhile Trump is working hard to preserve a -22 favorability rating.
PPP's new national poll, taken completely after both party's conventions, finds that Hillary Clinton emerged with a much more positive image than she had a month ago. Donald Trump meanwhile is just as unpopular as he was before the conventions.
Clinton's net favorability improved by 9 points over the last month. She's still not popular, with a -6 net favorability at 45/51, but it's a good deal better than the -15 spread she had at 39/54 a month ago. The gains are particularly attributable to Democrats increasing in their enthusiasm for her, going from giving her a 76/15 rating to an 83/12 one. Trump, on the other hand, is at a -22 net favorability with 36% of voters seeing him favorably to 58% with a negative one. That's barely changed at all from the 35/58 standing we found for him in late June.
