"What exactly is Jeb selling?"
I think he's become obssessed with "his" issue. You are either a "good guy" who agrees with him on illegal immigration, or somebody who needs to be cut off at the knees.
It's the same old song and dance that other wannabe reformers have used: "The GOP is on the 'wrong side' of a certain issue (global warming, bailouts, socialized medicine, gay marriage, public sector unions, etc., etc.) and unless the GOP adopts the Democrat position, it will be forever left in the dustbin of history"... (which of course has been proven wrong time after time).
You’ve got that right. Jeb and his GOP pals have done more than enough compromising with evil. We know where that road is taking us, and we don’t want to go there. Jeb should do us all a favor, and quit whining.
