I’m going to wait and see who Romney picks as his running mate, should he get the nomination. I’ll take that as a reasonable indication of how he’d pick the 2 or 3 SCOTUS appointments whoever wins in 2012 will probably get.
Beyond that, his running mate should be seen as pointing to the future direction of the GOP, since that person will be the defacto standard bearer if the ticket loses, or the natural successor if it wins.
I think the very fact that conservatives have such a dislike for Romney has gotten the GOP establishment's attention. If his running mate IS NOT a conservative then they will be handing the election to Obama. Many conservatives will still throw a Romney tantrum no matter what. But I'm hoping most will come to their senses and vote Republican if the VP running mate is a conservative.
