Trial balloon for "suspend the presidential elections."
Unfortunately, I think that you are onto something. The military, I think, would be split between those who felt that their oath to the Constitution would override obedience to orders given from above, and attempt to stop the suspension; and those who would simply be "following orders." There's a third element in this, those that would sit on their hands and see which side was winning.
Also, DPUG is onto something--they
know that they're going to lose
big in 2012. The 2012 election is the Republicans' to lose right now.
