I don’t have anything to add other than to note that stubby little fingers don’t bounce…...go read the actual article. A couple of quick quotes below (but go read the whole thing)

Initial polls conducted after the Democratic National Convention suggest that Hillary Clinton has received a convention bounce. In fact, it appears likely that Clinton’s bounce will exceed Donald Trump’s, which measured at 3 to 4 percentage points. Thus, Clinton will potentially exit the conventions in a stronger position than she entered them, perhaps also making up for some of the ground she lost to Trump earlier in July.
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.
