For all practical purposes, Roe, in combination with Doe v. Bolton, found an unfettered right to abortion throughout pregnancy. You seem to be trying to make the case that states lack the political will to challenge the decision, but the right to unrestricted abortion has been challenged by several states numerous times with little success, precisely because the court has so broadly defined the "right" to abortion.
-- Thank you, - that is exactly my case. - But the fact that challenges have little effect, points more to bad lawmaking & bad lawyers, than to any failure of our constitutional system.
As I said earlier, medical advances will soon allow 'pro-life' people to put there money up where there mouths are, - and 'save' unwanted babys with artifical methods. -- Two bits there are very few takers. -- In effect, they are pro-life, as long as someone else is responsible for nurturing & rearing that life.
