"On a daily basis there are some huge ones that are, sure, from time to time, but it is helping the reader sort through all this sort of gray stuff out there"

This quote by Jim Lehrer is referring to the large quantity of information offered to readers in the modern world. He is recommending that, daily, there are some big choices that require to be made, which it can be tough to arrange through all the clashing information out there. He is suggesting that, from time to time, it can be helpful to take a step back and sort through the "gray things" in order to make the very best choice. This quote is a reminder that, in the age of info overload, it is necessary to put in the time to thoroughly think about all the offered details before making a decision.
