I think the Specter issue will die down and that he will become chairman. However, I think once the new Congress convenes, pressure will be put on Specter to "get behind the President's agenda". He will get to save face and keep his chair, but he will be made aware that the party leadership will "pull the plug" if he steps too far over the line.
P.S. I envy you. I wish I could have been there.
We can maintain the pressure by simply not contributing to the RNC or the RSC if Arlen becomes chair. It is entirely loyal to continue to support Republican candidates, but to withold control from the party hierarchy of which candidates or how the money is spent. It will actually help the RNC long term if we do that because it will give the conservatives ammunition to make all future decisions on principle rather than tawdry electability politics.

All you need to do is write Heritage a check!
