Senator Palpatine and Darth Vader

Bush has issued a directive that would place all governmental powers in his hands in the case of a catastrophic emergency. If a terrorist attack happens before the 2008 election, could Bush and Cheney use this to avoid relinquishing power to a successor administration?

As my daughter says, Does this mean that Bush will be like Senator Palpatine and Cheney like Darth Vader, in the movie Star Wars episode 3? Could be. link
