Of course there is.
It’s only been a few days, and only three polls are out containing JUST data gathered after the end of the Democratic National Convention. But there are all good.
PPP has Clinton +5 (includes Johnson), Morning Consult has Clinton +3; CBS has Clinton +6 (with Johnson added, +5).
PPP measured likely voters, the other two measured registered voters.
Before we continue, a quick note or two about terminology. When we refer to a candidate’s “bounce,” we mean the net gain in her standing in the polls, including changes to her opponent’s vote share. For example, if the previous XYZ News poll had it Clinton 42 percent, Trump 40 percent, and their new poll has it Clinton 44, Trump 39, we’d call that a 3-point bounce for Clinton, since Clinton gained 2 percentage points and Trump lost 1 point.1
Also, when evaluating the gains a candidate has made, it’s important to note when the previous poll was conducted. Based on our models, Clinton led by 6 to 7 percentage points throughout most of June, but her lead dissipated to around 3 percentage points by mid- to late July, just before the conventions. Then, after the Republican National Convention in Cleveland, Trump pulled into an approximate tie with Clinton. It’s those post-RNC polls that make for the best comparison when describing Clinton’s bounce.
So far, however, the post-convention polls have been strong enough for Clinton that there isn’t a lot of need to worry about semantics. They suggest that she possibly holds a lead over Trump in the mid- to high single digits, instead of being tied with him.
What’s remarkable is that Trump seems to have gone down as much as Clinton has gone up.
Here is a Gallup poll released today. It isn’t a Trump v. Clinton poll, but it asked if the DNC/RNC convention made you more/less likely to vote for the Democratic/Republican presidential candidate. The results are telling.
If you look, it shows that — for the first time since this has been polled — Republicans were LESS likely to vote for their presidential candidate (Trump) after watching the RNC.
That is off-the-charts bad news.
