From CNN:

She says she is the Democrat best equipped to fight terrorists, but White House hopeful Sen. Hillary Clinton told New Hampshire voters Thursday that another attack on the United States would likely help Republican candidates at the polls.

"It's a horrible prospect to ask yourself, 'What if? What if?' " Clinton, a New York Democrat, told a house party in Concord, according to the New York Post and The Associated Press and confirmed by her campaign.

"But, if certain things happen between now and the election, particularly with respect to terrorism, that will automatically give the Republicans an advantage again, no matter how badly they have mishandled it, no matter how much more dangerous they have made the world."

There are two ways to interpret these comment. Naomi Wolf comes out in favour of the sensible one. Sample:
"Clinton is right to caution voters to consider the domestic outcome of a possible terror-related event before the election if you factor into her caution this forbidden subtext: if the terror scare in question is exaggerated, or even manufactured, to serve a domestic political purpose.

Even as I write those words, I understand I am breaching a major social taboo. There is a general polite consensus right now that maintains two no-debate areas. Firstly, you are not, if you are a serious person, allowed to note in public that it is possible that this White House or any US leader might conceivably distort or hype the terror threat for political purposes - although plenty of serious people discuss this possibility in private. Secondly, if you are a serious person, you are not allowed to suggest in public that it is remotely possible that in America elections could possibly be deliberately thrown off course any more directly than, say, the vote recount of 2000."

If Hillary Clinton is worried about it, the false-flag-o-meter must be off the scale.
