Sorry, but you have to attack Obama's policies and point out how destructive they are. If Palin runs, she is not necessarily running against Obama. She also stands for conservatism: Free markets, no corporate and government collusion, strong defense, pro-life, pro-gun, states' rights.
Again, if you're looking for a Republican who is going to give you a laundry list of proposals and bullet points of what the government can do for you, then you might as well say hello to a 2nd Obama term. You don't understand that people are tired of Washington and want to be left alone. Palin will talk about the need to reduce government and everything else will work itself out. She doesn't need proposals or a big platform of promises.
What do you reply to George Will's argument that small-government Republicanism is dead, because the People have turned their backs on small government and self-reliance?
That people want Big Government and its smorgasbord of services, from a Coast Guard rescue organization to the FAA to the Interstate Commerce Commission and Medicaid/Medicare?
