I'm going to be very unpopular after this, but I always felt Walter Cronkite broke the rules and wasn't a great example of what journalism should be. I love the fact he was irreverent to established power, but he was one man giving the nation the news, and it was often heavily filtered through his own politics. I understand why so many people think kindly of him in his passing, but I'll reserve my praise for Cronkite the journalist.
Like a Woodward or Bernstein?
Some would say Cronkite inspired Woodward and Bernstein.
