I think it's pretty interesting that there are no differences between the US and Canada as to the acceptability of the death penalty. I know that many Western countries that have abolished the death penalty still retain general public support in the 50-60% range, but I'm still rather surprised that our two countries are so close as to the moral acceptability.
I'm also surprised that both the US and Canada are so strongly opposed to human cloning. Apart from religious reasons (and even those are debatable), so long as there are proper regulations in place, I don't understand why it's so strongly considered to be immoral.
Overall, I wish there were at least regional breakdowns as to this polling. Considering they're social issues, I'm sure Quebec is pulling Canada to the left and the South is pulling the US to the right. I have to wonder if the US without the South might actually be to the left on many social issues compared to Canada without Quebec. (Also, looking at the poll on pornography, Canadians are probably fairly more honest overall than Americans.)
