Not knowing anything about how they came by that result, I can't really speak to how meaningful it is, but it was fun to look over the charts on their issues page. From it, I get the impression that liberals are uniquely unified in their views.
What shocked me most was the results of a survey on torture.
Overall, the public is divided over using torture against suspected terrorists when such tactics may yield important information. Roughly half (51%) say it is never or rarely justified, but 45% believe it is at least sometimes justified.That's just stunning.
Liberals are most strongly opposed to resorting to torture; 77% say it is rarely or never justified.
