Ryan Lizza

The New Yorker's chief political correspondent, Ryan Lizza, explains Joe Biden's relationship with Barack Obama — and why taking on less often means doing more as vice president.

Journalist Ryan Lizza says it's no accident that the Democrats picked Denver as the site of their National Convention. Lizza discusses the strategy among party officials to make inroads in the West rather than the South.

Barack Obama has been portrayed as an outsider candidate — an idealist not mired in the political game. But Ryan Lizza says that a look at Obama's political history in Chicago might offer a different view of the candidate. Lizza is the Washington correspondent for The New Yorker, and has been tracking the Obama campaign.
