The Washington Post:
Officials with the Democratic National Committee have accused the presidential campaign of Sen. Bernie Sanders of improperly accessing confidential voter information gathered by the rival campaign of Hillary Clinton....
Jeff Weaver, the Vermont senator’s campaign manager, acknowledged that a low-level staffer [now fired] had viewed the information but blamed a software vendor hired by the DNC for a glitch that allowed access....
The discovery sparked alarm at the DNC, which promptly shut off the Sanders campaign’s access to the strategically crucial list of likely Democratic voters.
I was once affiliated with a statewide campaign in which a low-level staffer was accused of having distributed an old photo of a Republican candidate shaking hands with Richard Nixon. The staffer, whom I was vaguely acquainted with, was accused for good reason: He was guilty as hell. The media-savvy Republican candidate labeled the Democratic staffer's behavior "dirty politics" — albeit, in reality, it was just about the least offensively dirty as dirty politics can get. Anyway, the local media went nuts, within minutes the photo-distributing staffer transfigured into another Donald Segretti, the staffer was sacked, and the Republican candidate went on to win the statewide race.
Change "Republican candidate" to "DNC" (i.e., "Hillary campaign") and it is photo-distributed-hand-shaking all over again, same "scandalous" magnitude, same housecleaning process, same outcome.
