I'd vote for Jim Lehrer and Tom Brokaw. If he were still alive, Tim Russert would be at the top of the list. And believe it or not, while I think he is definitely biased towards the right, I think Bill O'Reilly tries awfully hard to conduct tough, revealing interviews without injecting too much of his personal political leanings.

On the print side I like another writer who is often categorized as conservative, David Brooks of the New York Times. I think he presents the conservative perspective well, but is consistently willing to present a balanced view of the political news. Another print columnist that I read all the time who always presents a critical but thoughtful view is Tom Friedman, also of the New York Times. I've always thought that Friedman presents thoughtful ideas which, if they appear critical of one politician or party or the other, it's only because Friedman's ideas make such common sense or are based on reality as opposed to political posturing. In Friedman's case, even though he has decades of personal experience in the Middle East and can get access to almost any political figure in that part of the world, he seems to have "given up" on pure political commentary in favor of concentration on issues of the world economy.
