New York Times poll guru Nate Silver isn't backing down from his assertion that Barack Obama has a very good chance of winning the presidential election.

Silver was engulfed in a classic media controversy after a Politico article said he could be a "one-term celebrity" if Obama wound up losing. That article provoked a large backlash, and Silver sent several tart tweets in response:

"I think I get a lot of grief because I frustrate narratives that are told by pundits and journalists that don't have a lot of grounding in objective reality," he told Charlie Rose on Tuesday.
