And yet there are political scientists who would tell us that single-issue voting is classic democracy at work!

The terms "gun nuts" and "abortionists" are no doubt chosen with care, both being rhetorical and excessive; but I'm not sure the latter is the best choice to represent the abortion-on-demand crowd (it usually refers to the workers who perform the abortions). Also I'm not sure there is a moral equivalence between them. In both cases there is an anxious defensiveness lest some dignity or security be violated. But the gun-rights crowd think dignity and security depend on their being able to commit acts of deadly violence, which looks like paranoia; the ab.-on-demand crowd think these depend on full respect for women's bodies and minds -- and in fact it's an evident reality that women do not receive that respect.
