I completely disagree. I believe President Bush is a man of character and take him at what he's actually said. Apparently those in Mexico aren't the only ones playing with words.
My point is that it doesn't matter what you or I think. We aren't the only audience in this equation.
It's the perception of reality on the part of the emigre from Mexico that matters. They are told, or think they've heard, that President Bush is going to let them stay as long as they can make it across the border.
