There hasn't been any federal officeholder with the power of the presidency in his hands. I'm all for mormon forest rangers, federal marshals, secret service agents, and even old Orin, since he can't do anything unilaterally.
Don't think I would like Hillary to have taken a similar oath...oh wait...I think she did to Saul Alinsky
Saul Alinsky and the Lessons He Taught Bill and Hillary
A couple of Alinsky's teachings: "In a fight almost anything goes. It almost reaches the point where you stop to apologize if a chance blow lands above the belt."
"Pick the target, freeze it, personalize it, and polarize it."

Well, that's a different issue. They will fight dirty against any nominee. And lets face it, with Bush's unpopularity, 2008 is going to be a tough year for any nominee.
