Find a dupe – someone controversial and embarassing enough to draw attention away from yourself and your business. An alcoholic is good, as is someone who has driven multiple companies into the ground.
Steal an election to get dupe into power, have dupe start unpopular, illegal war to line the pockets of your friends.
Steal another election for dupe. Have dupe poke nose into all sorts of foreign politics. Make sure he ruffles feeathers everywhere. Have him destroy the economy to continue unpopular, illegal war. Ensure him a long enough rope to hang himself and his political party.
Choose a new dupe that will give the American people hope. Make him as different from any past president as possible, while still evoking the most popular of those past presidents. Let original dupe’s party self destruct. It should be so bad it drives people to vote for new dupe and his party. Since the American people will be full of hope for the future, they will happily elect new dupe without ever realizing that he actually works for you.
Profit! For added results, lather, rinse, repeat.
