If the goal of a convention is to expand a candidate's appeal -- which it is -- Trump's convention was a failure. But it's still hard not to think that Trump's convention was a missed opportunity. In other words, the Trump convention appealed to people who already liked Trump and turned off people who didn't. In the wake of the Republican convention, Donald Trump jumped ahead of Hillary Clinton in CNN/ORC's polling. By contrast, respondents said that the Republican convention made them less likely to back Trump by a 2-point margin.
