PHILADELPHIA — The Democratic convention began just as badly as the Republican one.

Instead of using the entire weekend to extol the virtues of new running mate Tim Kaine, Hillary Clinton and her aides were forced to react to the flaws of the Democratic Party chairwoman, Debbie Wasserman Schultz. Specifically, they were thrown off balance by leaked emails showing that Democratic National Committee staffers had, in fact, favored Clinton over her Democratic socialist challenger Bernie Sanders — something Wasserman Schultz had previously denied.
