mccain just does whatever his note cards tell him to.
Rubio just wants to be president, so he knows he has to have that hispanic base. You know, as repubs, the personal beliefs of most of them are "Close that border and leave some landmines to keep it closed..." - which I agree with too. You can put 50k troops in s korea, but zero troops on our border? WTF
However, since romney got a whopping 27% of hispanic vote... they understand the reality is they can't keep that position anymore. Facts is facts. I hate the idea of amnesty. But I see both parties embracing it. JUST WAIT til the 2016 GOP presidential debates, when Rubio and/or Jeb accuse other repubs of being "heartless" and "not caring" because they want to close the border. It'll make you want to spit on your own living room carpet in anger lol.
it is what it is.
