Unfortunately, you are right...however, do you believe that the left is so unintelligent to discount the possibility and risk political gain by putting aside such a possibility?
The left thinks it's a win-win situation for them: if we don't have a terror attack, they can make hey by attacking and trying to impeach President Bush, if we do have a terror attack, they can blame him for it.
They do NOT care how many hundreds of thousands of people die, what happens to the economy and the country, just as long as it gets them back into power.
It brings to mind the old story where Solomon had to make a decision: two women claimed the same child. So Solomon said to cut the child in half and give each woman half. One woman thought that was just fine. The other said, she would rather give up the child, just so the child isn't harmed -- the Republicans act this way, they care for the country. The Dems act like the other woman, they rather see the country destroyed, just so Republicans don't lead the country.
