Philip Klein points to a new CBS news poll (again, it's a CBS poll ... I'd be interested in what Rasmussen would find) showing that nearly six in ten Americans don't think the political tone had anyting to do with the Tucson shooting:
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.As Klein goes on to note, when even a plurality of Democrats don't think harsh rhetoric had anything to do with the shooting, it's clear that liberals' desperate attempts to pin this attack on conservatives have been failing. This is largely a result of the fact that a) there has been no evidence to support such a link and b) conservatives did a good job pushing back against the left-wing effort to exploit this tragedy.
Perhaps it would be appropriate to also add that, as mixed up and loony as the Arizona shooter indeed is, whatever ideology he actually has (insanity has no set ideology) - it's far more Left than Right. However, even given his leftist bent, there's no way to attribute his evil act to any particular leftist rhetoric or personality.
