Judge Sonia Sotomayor may have some trouble with the left since she did not rule on many right to privacy challenges. I think the Democrats have to ask some tough questions to see if she believes that (a) there is a general right to privacy, (b) that this general right to privacy must include a right to private non-procreative intimate conduct between members of the same and members of the opposite sex and (c) whether that privacy right includes, at least a disposition to favor a pregnant woman's right to terminate a human embryo or fetus within the first trimester.
No judge who is inclined to overturn the right to privacy should be appointed to the Supreme Court.
Now it should be noted that the cited abortion cases concern immigration law (as it applies to political/moral dissenters) as an example. but it shoudl still be asked.
