DeLay didn't cost us a damn thing. Some bought and paid for "prosecutor" brought charges against him after he shopped around for a compliant grand jury then refused to let DeLay have his day in court. Rouge prosecutors on the payroll of political hacks or out to make a name for themselves by bringing "charges" (see Duke rape case) are a new threat to the country. Not Tom DeLay.
One real danger of having millions of unassimilated immigrants from undemocratic countries here is that they do not understand or believe in democracy. You can pick that up many places, especially in the cynicism of democracy for Iraq. It is also writ large on the Democrat methods of seizing and weilding power. They are totalitarian elitists, not democrats. They are progressive only in the sense that their mentality is 1900.
