A few have, but not Roberts, Alito, Kennedy, Breyer, Ginsburg, Kagan or Sotomayor. Privacy is bound in precedent and the body of law on it has grown to the point that it cannot be reversed.  Thomas argues that the Court could change the terms of Chapter X of Roe and set an earlier time for the start of life. Gorsuch will likely go with Kennedy.  If Congress acted, it would not change much and would essentially ratify the current law, with some possible protection for Downs babies (probably not, however).  I wish they would - it wound end the issue and its usefulness in putting idiots like Trump and Bush in office. (at least Laura Bush had the last laugh, her husbands appointees vote with Kennedy on abortion).
