But Roe and the cases that set up Roe with all of the eminations and penumbras were badly decided. A constructionist will chip away at that logic. But Roe will hold on by a fingernail even if all of its legal underpinnings are destroyed.
That is 100% correct. And it will take time to chip away at the precedents. I wouldn't expect any formal action on Roe v Wade for at least 5 years.
