McCain has a point.  The present Republican Party is like a snake eating its own tail.  The Republican base has a lot of anger and it's showing up in this process.  It's a case where the far right wants to offer nothing and the more moderate right wants to offer an uncompassionate plan that would throw millions off health care.  I hope they listen to McCain, but  I don't think anything the Republicans will come up with will be very good for anybody.
