Poll: Americans Don’t Blame “Political Tone” for Tucson Killings
slate.com

Overall, 57 percent of respondents said the harsh political tone had nothing to do with the shooting, compared to 32 percent who felt it did. Republicans were more likely to feel the two were unrelated - 69 percent said rhetoric was not to blame; 19 percent said it played a part. Democrats were more split on the issue - 49 percent saw no connection; 42 percent said there was.

That’s still around a third of the country that blames rhetoric for the attack, despite evidence that it had nothing to do with it.
