Via our old pal John Cornyn (don’t ever say he’s totally worthless), here’s a copy of the aforementioned Senate GOP letter that says Republicans won’t agree to do anything in the lame duck session until Democrats have done everything Republicans want to do. The letter, which Cornyn says was delivered to Senate Majority Leader Harry Reid this morning, has 42 signatures, which represents enough votes to block consideration of any legislation Democrats put forward, including a repeal of “don’t ask don’t tell.”
