Jim Lehrer would not last five minutes in network television. His career would be even shorter on cable TV.
Despite his many awards and accolades -- all deserved in my opinion -- Lehrer would not stand a chance of getting hired in TV today, especially on cable. For one thing, he is not a yeller. He is not a bad looking guy, but he is no Brian Williams either. As Lehrer told Stephen Colbert, "It takes guts to be boring."
About the only wacky quirk I was able to find out about him was that he is an avid collector of bus memorabilia, which he likes to purchase on eBay. He is a serious journalist and the show proves it. The only time the name of Anna Nicole Smith was mentioned on the program was when a case involving her made the Supreme Court.
