Given the current popular consensus, second and third-trimester abortions would be permitted with some reasonable regulation. The different compromises reached by different states would both reflect and alter the culture and character of the states. Thus different states would provide separate experiments as to consequences of different approaches to abortion. The results would inform future decisions. Ultimately in a democracy one must trust the people.
Abortion is an issue that can safely be entrusted to the polity.
One result would be a healthier democracy and greater deference to courts when they are required to make controversial judgments of law.
