This may well be true; I think Bush is a terrific President: an honest man who has integrity. I do not doubt his concerns are genuine for our country.
OTOH, why is he so angry with Tancredo? Tancredo has legitimate concerns (and his views represent most Americans'). It is not only Mexicans who are crossing illegally (and using up all our resources: taxpayers are paying for their medical treatment, schooling, welfare programs, food, etc.), there are also illegal Middle Eastern men crossing over....and 99.99% of the terrorists are Arabs. Why are we allowing them to flow into our country at the border and only attempt to stop them at airports? Seems ridiculous to lock the front door if you leave the back ones open.
Who said he was "angry" with Tancredo?
