Richard Clarke and Roger Cressey, from the New York Times:
There is, of course, another possible explanation for all the outraged bloviating. It is an election year. Karl Rove has already said that if it were up to the Democrats, Abu Musab al-Zarqawi would still be alive. The attacks on the press are part of a political effort by administration officials to use terrorism to divide America, and to scare their supporters to the polls again this year.
The administration and its Congressional backers want to give the impression that they are fighting a courageous battle against those who would wittingly or unknowingly help the terrorists. And with four months left before Election Day, we can expect to hear many more outrageous claims about terrorism — from partisans on both sides. By now, sadly, Americans have come to expect it.
