Jay Sekulow of the conservative American Center for Law and Justice (ACLJ) claims that Judge Sotomayor is strict on the separation of church and state, meaning she would've voted against allowing the display of the Ten Commandments on public property had she been on the high court. Jay did not cite any cases to support his position, and it will be interesting to see what he gives us. But, according to this New York Times article, in 1993, "she struck down as unconstitutional a White Plains law that prohibited the displaying of a menorah in a city park." So she doesn't seem to be someone who wants to ban religion from the public life.
But we'll learn more in the coming weeks.
