It basically starts with Obama's claims of economic success and his promises of the past followed by a narrator who says during his presidency he has constantly claimed that he is making progress with the economy while millions have been forced to the unemployment lines and onto food stamps, and many more have struggled. President Obama has spent vacations in Hawaii, more days playing golf than meeting with his economic policy team and traveling from city to city, raising millions of dollars with movie stars and celebrities. Barak Obama speaks one way, but his actions are completely different.
Now, that's just a start. Every time the Obama campaign comes up with a nitpicky new issue that they focus on, the GOP and Romney should swiftly take to the air with ads pointing out how bad the economy is. That the programs he passed resulted in no improvement. That he has run a secretive administration in which agencies target individual citizens. Drones are ordered to fly over our homes, and mandates move us closer to old failed systems of government -- "hint," can you say "Soviet Union"?
The last part of the strategy would be to prepare for the debates early on. While most people believe debates make no difference, they in fact were the determining factor in Kennedy vs. Nixon, Ford vs. Carter, Reagan vs. Carter and, to a lesser extent, George H.W. Bush vs. Dukakis. A knockout blow by Romney in those debates might just turn what had been a meandering campaign into a winner.
