No. Stubby was just mentioning a couple of things that Russert was known for doing. It was his job and was factual, not politically biased. He was well respected for it too, because you knew he'd keep his personal beliefs and views out of things and give you only the truth.
I may be wrong on this but I think he was a republican. Despite that, from what I've seen of his coverage of the upcoming election, he's been quite candid in pointing out that Obama has a good chance of defeating McCain. He's also made points to the contrary, but all his points were based on polls and events.
