Is beheading more humane than long winded chemical and electricity executions?

Why is the US always so far behind other countries in so many areas? Lois
The Religious Right controls Republican primaries. And Republicans, apparently. I want to think this is the only reason, but I think there must be more to it. Lois I am sure there is more to it, but everyone I know who supports the death penalty is a conservative Republican and a Christian. I'm not a sociologist and I've never played one on television, so take this with a large grain of salt. I would support the death penalty, in theory, in certain extremely limited cases, if it could be applied justly and equitably, and if it could always be applied with absolutely no execution of persons who are, in reality, not guilty. Neither of those two "ifs" are in effect in our country, nor, do I suspect, can they ever be. Hence, we should immediately ban the death penalty.
