I think when Obama ceases to be useful to his inventors, that a tragic ending with a right-wing patsy is not beyond what they are capable of.
Your scenario is not at all far-fetched if our mutual assessment of the nature of the Obama administration is at all accurate. One need only contemplate the fate of Robespierre, Trotsky or the victims of the Cultural Revolution to understand what happens when leftist radicals get power.
The idea that there is an inventor behind-the-scenes is not far-fetched either when one contemplates the role of George Soros in all of this and I assume that is the reference which you intentionally left unmade.
My thesis is that leftists are God playing egoists and as such they are jealous gods and will tolerate no other gods before them.
