Boy do you have this wrong.
Agreeing to the Senate Rat demands of a clean bill is a sell out of campaign promises to STOP the illegal amnesty program. If Boehner stays strong and won't agree then it is the Pubs who shut down DHS. If McConnell really wanted to win this fight he would have ended the filibuster, passed the bill, and sent it to obama. Instead he gave in to the Rats.
Why support Pubs when they don't support you.
Basically they do...and the alternative that you suggest would be??????????????????
