Media World: Why David Gregory is no Tim Russert

"Meet the Press," which has been part of the American political landscape for more than 60 years, has been losing viewers ever since the death of its beloved longtime host Tim Russert last year.

David Gregory, the network's former White House correspondent, was named the host of the marquee NBC News program in December. He is a smart guy and capable journalist. But he has the unenviable task of following in the footsteps of a legend who was the king of Sunday morning talk. As the Washington Post pointed out, "Meet the Press" has shown itself to be quite mortal over the past few months.
