Close, it sounds like they all agreed it should be enforced federally. The liberal justices plus Barrett didn’t agree with saying congress was the only federal institution that could enforce it. So the liberal justices plus Barret may have opened a path for a federal lawsuit to prevent him from taking office or being on ballots. As it is with the current ruling, only congress would be able to stop him, either by passing a new bill specifically laying out how insurrectionists will be barred from ballots, or possibly by refusing to certify his electoral votes after the election.
