Considering the sources - a former Bush national security official and a prominent terrorism expert - this is not good for Bush.
From Reuters:
One former national security official in the Bush administration told Reuters: "This is more butt-covering than anything else."
Critics say the new threat warnings may also just be a ploy to shore up the president's job approval ratings or divert attention from the increasingly unpopular Iraq campaign....
"It's like the old Wendy's (fast food) commercial: 'Where's the beef?"' the former Bush administration official said....
One prominent terrorism expert, who would only speak on condition of anonymity, said Bush may also be trying to staunch increasing criticism of the Iraq campaign by underlining the link in the public's mind between Iraq and security at home.
"The president is running as a war president, so the timing is interesting," he said, pointing to a speech by Bush on Monday that made frequent references to terrorist threats.
"I wonder if there's not a connection to the president's speech when he mentioned terrorism 18 times in the context of Iraq. Isn't this a very convenient way of linking back to the United States that Iraq is part of the broader war on terrorism?" he said.
