The press doesn't just cover presidential campaigns, they influence them by making arbitrary decisions about who is 'top tier' and merits coverage.
Now personally, I think the president should golf every day and never have a press conference. I want the leader of the free world to be as stress-free as possible. And if golf helps fade the psychic heat from the job, by all means tee it up often, Mr. President.
I think that the press has a duty and an obligation to report on local government, state government, federal government - to be aggressive, to do its job. And its job is to report on whatever it's covering.
