The truth about the U.S. political system over the past 25 years is that presidential choices have narrowed down to an ongoing contest between two elite schools, Harvard and Yale. If Vladimir Putin wishes to stop being an amateur at rigging a political system, he should study how system-rigging is done in the United States.
Here are the recent winners of the U.S. Presidency:
1988: Yale (beating Harvard).
Note that George W. Bush covered his bases by being a grad of both places.
It appears from the list that Yale has the upper hand-- but 2012 will likely be a battle of Harvard vs. Harvard. After all, it's still Harvard's turn.
