 There's a lot of reasons to be suspect of that argument, in part because nothing else has seemed to change anything. But then again, we haven't had anything like this in decades. We haven't seen a presidential candidate attacked, an attempted assassination of a presidential candidate in so long that there's not really an obvious analog. And it's easy to see a scenario, especially with what amounts to a four-day free commercial for a party at any convention is, it's easy to see a scenario where, wow, Donald Trump looks a lot better at the end of this week, and that might actually translate into the polls.
