Two of every three GOP SCOTUS appointments support not repealing Roe. Gorscuh replaced and admired Scalia, but was Kennedy's clerk. At best, he keeps the vote on repealing Roe at 7-2 against. If he follows Kennedy, Roberts and Alito, it will be 8-1. Remember that every potential Justice is somewhere in their 50s and are young enough to have had Roe as part of their curriculum in law school and it is always on the test. Only a few select schools teach an alternative analysis on the case, which, by the way, is fringe.
