SHIELDS: "I think the timing was better. If anything, she did need a lift this week. After Comey and the e-mails and after Dallas and after Baton Rouge and after Minnesota, she needed — Secretary Clinton needed a lift, and I think Bernie Sanders’ endorsement gave her a lift. If it had come two weeks earlier, as so many Clinton folks were urging and exhorting him to do, I don’t think it probably would have given the kind of upper that she did need at that time, even in the midst of a week in which it was very much eclipsed."
