… to find problems with this assessment in the latest Newsweek:

Recent decisions saw Alito in the majority, voting almost in lockstep with Antonin Scalia and Clarence Thomas. Court watchers are waiting to see if any case splits the conservatives?to find out if Alito is radically or only moderately conservative. 

What does “almost in lockstep” mean? How could a split among conservative justices in a single case reveal whether Alito is “radically or only moderately conservative”?

What does “radically conservative” mean? Isn’t that a contradiction in terms?
