Media Matters has been desperately trying to point out something which should be obvious to 8 year olds - that Circuit Court judges don't have the power to overturn Supreme Court rulings.
The press is repeatedly saying that Roberts' confirmation hearing statement that Roe was "settled law" is meaningful. But, it doesn't have any meaning over and above the obvious - that Supreme Court rulings are the law of the land until the Supreme Court revisits an issue. Roberts could've given that answer about literally any SCOTUS ruling, and it would've provided no information about how he, as a SCOTUS judge, would rule on a particular issue.
