He certainly does know. The problem is, and it will be with any president, unrestrained immigration has brought millions of people to this country who are anti-American, and who can't wait to see our destruction as a free nation.
Bush is trying to make peace with these people because he needs their votes. They have lobbyists in Congress threatening our elected officials if they go against immigration, or tell the truth about the Muslim religion. They have many attorneys throughout America who work night and day to steal money from the tax payers, circumvent our laws and negate our votes, and again our Congress is too terrified of these subversives to do anything against them. (Like kick their treasonous arses out of America.)
