The most important thing about this is not the statement this will make about the need for conservatives in the GOP(there will be a lot of Bushies who will bend over again to get Specter relected so this does not happen), but the replacement of the GOP point man on judicial nominations review on committee.
The latter will need a person with spine who will challenge in every way possible Obama’s selections as he attempts to remake the judiciary the way he is doing to the executive.
A SPINE? Well, that eliminates almost every single Republican in the U.S. Senate right there.
