If you allow more and more of those in your midst to take on more and more of the form and substance of the opposition...you ultimately become the opposition. That is the issue with Specter. It does not apply to that degree in all of the races...but it does in this one. IMHO, removing him will send a message to the others that in the end will be very critical to the overall future of the GOP.
Other than that, I can agree with most of what you said in this last post.
My only other point was that you should take some time to check into the background, position and tireless activism of other posters before you label them as you did Joanie-f in your prior post.
