From the Dailyjolt Politics Forum:
So, if a terrorist attack doesn't occur, it can be used as a sign that Bush is successfully fighting the terrorists. If an attack does occur, it can be used as a sign that the terrorists don't want Bush to be re-elected.
This is awfully convenient, isn't it?
I should say so. And I'm sure we'll be hearing more along this line from right-wing pundits soon.
