Could it be because it's true...?

Why is it that Democrats seem focused on the political effects of a terrorist attack and the Republicans seem focused on stopping them?

Hill: Terror Would Be GOP Boost
The Washington Post

WASHINGTON - Sen. Hillary Rodham Clinton yesterday raised the prospect of a terror attack before next year's election, warning that it could boost the GOP's efforts to hold onto the White House.

Discussing the possibility of a new nightmare assault white campaigning in New Hampshire, Clinton also insisted she is the Democratic candidate best equiped to deal with it.

"It's a horrible prospect to ask yourself, 'What if'? 'What if'?" 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," Clinton told supporters in Concord.
