Not just the WOT. There's no way they will appoing the same kind of justices to the Supreme Court. McCain will use John Roberts as his model. Hillary/Obama will use Ruth Ginzburg.
The WOT is just one of them.
Just speculating, but I think he'll be more likely to use Anthony Kennedy as his model. A John Roberts nominee, aka a staunch conservative, could not be described as "reaching across the aisle", which McCain so loves to do. An Anthony Kennedy nominee, aka a liberal Republican who can be counted on to vote with the liberals at least 45% of the time, would be much more palatable to the libs.
