The latest entry on the Los Angeles Times politics blog comes from a new — but no longer unexpected — source. It's credited not to one of the Times' bloggers (Andrew Malcolm or Don Frederick) but to Mark Silva. Who?

Mark Silva writes for The Swamp from the Chicago Tribune's Washington bureau.

Ah, The Swamp, the Chicago paper's politics blog. Maybe The Swamp has written items for the Times before, but if so I missed it. But as The Swamp said last year, "We have officially become the blog for the Tribune Company's Washington Bureau, home to not just the Chicago Tribune, but the Los Angeles Times, Newsday, the Sun (Baltimore), the Hartford Courant, the Orlando Sentinel, the South Florida Sun-Sentinel, the Morning Call (Allentown, Pa.) and the Daily Press (Hampton Roads, Va.)" In a Sam Zell world all content is interchangeable.

Noted: Here we are in the middle of a pretty interesting election year, but nonetheless, the lead editor (Tom Furlong) and researcher (Nona Yates) on the LAT's national campaign desk have put in for the buyout and could be gone within the month.
