Terrorist threats politiced?

“I am concerned that every time something happens that's not good for President Bush he plays this trump card, which is terrorism. His whole campaign is based on the notion that "I can keep you safe, therefore at times of difficulty for America stick with me," and then out comes Tom Ridge. It's just impossible to know how much of this is real and how much of this is politics, and I suspect there's some of both in it.”
Howard Dean's reaction on CNN after the raise of the threat level.
