I found this info from www.redstate.org "Roberts is married to the former Executive Vice President of
Feminists for Life."
They also go on to point out that his two children were adopted and he ended his announcement with "I also want to acknowledge my children, my daughter, Josie, my son, Jack, who remind me every day why it's so important for us to work to preserve the institutions of our democracy".
This could be seen in a similar "secret signal to the right" as Bush's statement that Dred Scott was the worst SC decision ever (also a code to the right to life movement).
