You misunderstood. You were intimating the fact that Mrs. Roberts appears to be pro-life is a good indication of Judge Roberts' position. I said that President Bush's wife is pro-choice. That would seem to defeat, or at least compromise, your conclusion.
If she should be a leader with a intellectually responsible pro-life organization that would be a good indication that Judge Roberts is sympathetic to pro-life causes.
Mrs. Bush has not been outspoken on the issue.
