If for no other reason than the gems of tempered good sense and reason he gives us. First he called Miami a Third World Country. Then he expressed his disbelief in the bedrock theory of all modern biology. And now he believes it a matter of good sense foreign policy to point weapons at Mecca and Medina in a manner that conjures up for me images of the Tyrannosaurus in Jurassic Park waiting for the kids to move in a way it found interesting.
Tancredo apparently thinks it a good idea to threaten the Muslim world with immediate retaliation against Mecca and Medina if another terrorist attack occurs in the US. Aside from the fact that you have to be almost a sociopath to believe it is moral to blindly attack people for an action in which they had no complicity and that it would unleash a paroxysm of anger making the current situation look tame, he successfully channels the right wing thought stopping politics of resentment where if knowledgeable experts call you utterly out of your mind it is somehow a badge of honor.
