Conservatives need to borrow a page from the liberals' playbook and learn incrementalism.
Which is not necessarily a bad thing. Right now, Planned Parenthood and their ilk concentrate on nationwide efforts, whereas the many pro-life organizations, large and small, tend to operate on more local levels. If RvW is overturned, PP will be forced to split its national effort into 50 smaller efforts. I don't think PP has the personpower for such an effort. I have read that they have fought things like this so vociferously in the past -- not just because they're pro-abort, but because they in no way have the resources to fight 50 individual battles, at varying levels of complexity, with thousands of state politicans to be schmoozed and shnookered.
But throwing everything back to the states won't end abortion. If you leave it up to the states, it will always be legal in NY, Mass, and a lot of others. The only way to end it once and for all is through a federal law.
