Maybe he was saying that, I was listening but also doing something else at the same time, so perhaps I heard it incorrectly. That was my distinct impression, and I think Rush’s also, because Rush would have the same concern you did for the exact same reasons.
At any rate, until we secure the border, nothing else matters a bit. NADA.
He said what you said he did to try to sell amnesty, by getting us to conclude the two would be the same.
There was no other reason to use it as a reply to Rush's comment on it.
He knows if he said ‘those getting amnesty will vote Dem unless Rs move to the left’ would be the kiss of death for his proposal and maybe him too.
