I seriously doubt that this is even true, but even if it were, I doubt Obama would be successfully impeached.
I am comforted, however, to think that Arlen Spector will not be here to cite “Scottish Law”.
I don't agree with your first point, but agree with the second.
Indeed, this is not new talk... the context from months ago was that the "hostage" being referred to was none other than the Blind Sheik... a live Stevens would be traded for a live Sheik. However, a dead-Stevens - live Sheik trade doesn't look so hot, especially for purposes of the November election.
I agree with you. If this is true, the best we can hope for is that it will receive enough media coverage to negatively impact Obama's poll numbers for the remainder of his presidency. The big benefit would be that it would damage Hillary's credibility to the point where she would have to forget about a run for the White House in 2016.
