CNN, December 1-3
The NBC/WSJ poll goes back to 1997, and these are her lowest "Very Negative" numbers in the poll since three days after Bill Clinton admitted his affair in 1998. The CNN poll goes back to 2006, and these are by far her best numbers ever.
We don't have any post-election, pre-SoS readings for her, so it's a bit hard to tell whether post-election love for Democrats is playing a bigger role, or whether it's the attachment to a popular president. Both are probably factors.
