That you are suggesting because GWB doesn't meet with certain people (or groups) personally that, that in itself means anything is utterly foolishness (just like the silly assertions the NAACP makes).
Furthermore GWB has met all sorts of people and we have whole segments of our Gov't devoted to the issue of immigration. It is utterly absurd to suggest because the President can't fit everyone into his schedule that would like to talk with him.....that that means he doesn't really care about whatever issue they want to discuss.
It is childish to suggest such.
