Slate Also Has Defectors
Slate just published their own editors votes. Interesting point: Obama's support in that group dropped from 96 percent to 83 percent -- in other words, 13 percent "defected", which matches quite well with the Washington Post polling I reported in "Keep Calm and Finish Him".
Once again, Obama had 53 percent of the vote in 2008. 87 percent (100 percent minus 13 percent defections) of 53 percent is 46 percent.
