I understand. Just think of another Ruth Bader Ginsberg nominated for the Supreme Court.
McCain isn’t great but he is better than Obama or Hillary would ever be. The Supreme Court alone would mean decades of influence, not just one presidential cycle.
A point well made and impossible to refute. However, McCain is liable to do almost anything. He could appoint his friend Fred Thompson despite disagreements on amnesty, CFR (Fred wised up), a few lesser issues. That would be wonderful and I would vote for him just because of that.
OTOH he could appoint Hillary "in the interests of healing and bringing us together".
