Brinkley's Beat--And who are some of the great journalist writers?

I am almost 3/4th the way though 'Brinkley's Beat'. The man is a damn good writter. His treatment of Theodore Bilbo is really excellent; his creative juices were really flowing. After reading this book, I will read more by David Brinkley. "Washington Goes to War" is said to be excellent, is his personal best seller, the book he took the most time with, and has interesting views on Dixiecrats like Theodore Bilbo.

Theodore Bilbo was a US senator from Mississippi during WWII who ran the committee which oversaw the District of Columbia. The man didn't exactly hide the fact that he was a rasist in fact, he was one of the most outrageous racists to ever serve as US senator. He made international new during wwii, the worst thing about NAZIs was that they declared war on the US according to Bilbo, and he was friend to all the major anti-semites in the media.

Grammar studies still have my attention. Recently, I spend $132 on books and all were on on grammar, but for David Brinkley's book. I feel a new reading interst coming on. I want to read leading journalists writings. After I'm done with Brinkley, I will start anouther.
Who do you think merits my attention and why?
Which journalists do you hold to be best, or your favorite?

On my suggestion list are: Charles Karault, Mike Royko (wrote Boss), Arnie Pile.
