Could Cheney's private army act on US soil to attempt a Republican coup?

Could Cheney's private army(Blackwater or whatever they are calling themselves now) act on US soil to attempt a Republican coup against the duly elected government?
Since Blackwater is almost all Special Forces veterans (Army Rangers and Green Beret's, Air Force ParaRescue and Pathfinders, Navy Seals and Marine scout snipers) would they not be ideal troops to stage a coup for their boss Dick Cheney to put the Republicans back into the whitehouse?

He's on CNN and Fox News regularly, trying to drum up support for a coup. If he did, no doubt Hannity, Beck, and O'Reilly will do their usual dance of delight as they watch him shred the Constitution.
