I think this test case is not going to end well.
this test case will be tossed by lower courts based on precedent, and the SCOTUS will decline to hear it.
Roberts is not stupid. he knows he is one vote short, and doesn't want to alienate Kennedy, who would be willing to go along with restrictions on late term and parental consent laws, but not toss Roe with respect to adult women in the first 10 weeks.
