Rank speculation suggests that he may drift somewhat, but not a whole lot. Roberts' intellectual confidence points to a man unlikely to be swayed by the siren song of the opinion pages, and his ability to get along with everyone suggests that he may not only withstand Scalia's barbs but could assume the role of leader of the conservative wing—attracting moderates like Kennedy and Breyer back to the fold. Roberts' extensive experience in the executive branch and his role as successful advocate for conservative positions means he likely has a well-thought-out judicial philosophy on hot-button issues like abortion and gay marriage, and that, unlike Souter or O'Connor, he won't be crafting his views as he goes.
