From a CNN press release:
Award-winning journalist and best-selling author Carl Bernstein, best known for his reporting work with Bob Woodward about the Watergate scandal, will join CNN this election season as an analyst, it was announced today by Jon Klein, president of CNN/U.S. He will appear on the full line-up of CNN’s broadcasts and election coverage.
Aside from the fact that he's clearly a throwback to a previous generation (if CNN existed in 1975, this would have been a coup), it is unclear what qualifies this journalist would be a good political analyst.
As one respected journalist, who wished to remain nameless, told me: "Ideology aside, the guy knows zero about politics."
