Ahh ok I see what you mean. Given how Roberts acted with the Obamacare challenges and immigration...I'm with you...he doesn't have the stomach for it.
Or, perhaps, he's too much of a principled conservative for it.
Roberts is right that the status and authority of the Court is compromised when it wades into the political arena. And nothing is more politicized than abortion. The Constitutional amendment process is the proper means of rolling back Constitutional rights and protections (or granting new ones, such as to the unborn). For all the squawking about Roe not being grounded in the text of the Constitution, there's absolutely no basis in the Constitution for extending the rights of a citizen to a non-viable fetus.
Is changing the Constitution by amendment easy to do? Of course not - and that's by design. After forty years, women have settled expectations concerning their rights, and will fight to protect them. That reality should not, however, justify judicial activism as an acceptable alternative to following the procedures set forth in our founding document.
Justice Roberts knows that, and so does, I hope and believe, Judge Gorsuch.
