Lambert Strether annotated this tweet by the president of CAP (the Clinton-supporting Center for American Progress):
A few people have posted links to "expert" opinions that the Russians hacked the DNC. This is exceedingly hard to prove but who cares anyway? If you start talking about Russians at this stage of the American election we know who you are voting for. Poking a stick at the Russian bear -- smart campaign tactic! (Did you know they have nukes?)
Update: This Tanden person is a loose cannon who is rumored to be in line for a Clinton administration top job. Yikes.
Update, December 3, 2020: The "loose cannon" link above went dead so it's been switched to the Internet Archive version.
