Furthermore, Wang reports that a new CNN/ORC poll after the convention states that 44% of respondents were less likely to vote for Donald Trump while only 42% were more likely to do so. That certainly doesn't sound like a convention bounce.
So the election is not today. I am not denying that the Hillary Clinton campaign has a great deal of work to do. And in watching the opening part of the convention this evening, the focus has been on old-fashioned identity politics, as it is called, with little or no focus on actual policy proposals which would help all people economically. Perhaps this will come later on.
For now, polls should be looked at critically. They may, however, help prevent over-confidence on the part of Democrats -- because over-confidence is not justified and dangerous.
