I've pretty much gotten to a similar point of resignation with our two RINO Senators from Maine; SNOWE and COLLINS, neither one of whom seem to have ever seen a tax or an abortion that they didn't like.
They will, in all probablility, be siding with the Hitlary/Teddy K. faction on this one, as they are rather wont to do.
I've previously written and called them so much that I have probably been on their "Kook List" for quite some time now.
Good Luck!
