My Erasmus Darwin post got such a huge response that a follow-up is in order!

Law-makers are responsible for the laws they make, and support, and do not repeal. They are responsible for the intended effects of their legislation, also for unintended but easily predicted effects.

None of this is mitigated if mediated through a causal chain that includes other actors besides the legislators.

If law-makers favor legislation that makes it easy for immigrants to enter the country illegally, they are faulted (or credited!) accordingly.
