Now, this poll looks fine.
Looks like Clinton got a bounce that was 1-2% higher than Trump's (she was up by 3-4% before the RNC).
I'm in general agreement with you, but don't convention bumps take several days to totally manifest themselves in the polls?
Also, I have a hard time seeing Hillary not getting at least into the high 70s among Hispanics. One issue I've seen raised is that a lot of pollsters don't poll Spanish speakers. I don't know how much truth there is to that point, but I'd imagine it would underestimate Hillary's support among Hispanics by several points.
