19,000 internal Democratic Party emails released on Friday by WikiLeaks [set] off a frenzy on the eve of the party's quadrennial nominating convention and forc[ed] the resignation of the party chairwoman, Debbie Wasserman Schultz. Some of the emails revealed internal discussion by D.N.C. officials - obligated under party rules to remain neutral in the presidential primary - about how to discredit Senator Bernie Sanders of Vermont, enraging some of his supporters. Some ... are highly critical of Mr. Sanders. But the leaked cache also included thousands of emails exchanged by Democratic officials and party fund-raisers, revealing in rarely seen detail the elaborate, ingratiating and often bluntly transactional exchanges necessary to harvest hundreds of millions of dollars from the party's wealthy donor class. The emails capture a world where seating charts are arranged with dollar totals in mind, where a White House celebration of gay pride is a thinly disguised occasion for rewarding wealthy donors and where physical proximity to the president is the most precious of currencies. Donors who raise $1.25 million for the party - or who give $467,000 - are entitled to priority booking in a top hotel, nightly access to V.I.P. lounges and an "exclusive roundtable and campaign briefing with high-level Democratic officials," according to a promotional brochure obtained by The Times.
