Calderon might want a semipermeable membrane for a border, but his whining about Arizona is in regard to Arizona LEOs enforcing federal immigration law being de facto racial profiling well beyond any sort of border.
Calderon's visit strikes me as a Kabuki dance orchestrated for the November's election done as a favor for the rats to rally their base. Only the hard left wants another amnesty, whines about racial profiling even when there's no proof of it and wants a renewal of the so called "assault weapons ban."
Whining about racial profiling will remain as long as different races intermingle, IMHO, but there's probably no chance of another amnesty while the economy is in the crapper or a renewal of an assault weapons ban after 65 rat members of the House sent a letter to Holder last year telling him to fuggitaboutit.
I didn't watch the speech, but if I had to guess, there was no standing ovation for Calderon when he asked for a renewal of an assault weapons ban.
