These multiple campaigns against Spectre will ultimately have little impact on that decision (other then to make Spectre squirm a little more) but will work against some of those pushing them. Many of these attacks have gone too far in how ugly they are, and are now spilling over into the AG nominee. What next?
As for the scorched earth demands and threats, that is counter productive. People are burning their bridges...before they even get to them. There hasn't been a single Supreme Court nomination made and it's already become an ugly war.
What's it going to be like when the Senate seats Spectre and the President has his AG confirmed?
The problem is that Specter has a track record of dishonesty on Supreme Court nominations. He flat-out LIED about Bork and the nature of his contacts and talks with Bork.
If he is seated as committee chair (or on any committee), it must be done on a conditional basis. If he gets out of line, he needs to be automatically booted from all committee seats.
Being chairman of the committee is a position of special trust and honor. He hasn't satisfied me that he actually deserves said trust and honor.
