Why would you dismiss the possibility that Vicente Fox persuaded Dubya to initiate this?
I would not dimiss the possibility - but I would say GW might come up with it on his own since Tancredo's blast are actually aimed at the man or administration responsible for the situation today. That is not Bill Clinton, although he is to blame for many coming here, GW is responsbility for their staying here and for the ones who have come since he became President. He is actively encouraging their coming - so I would say he probably holds no love for Tancredo, and would certainly like to discredit him.
