PALIN CONFIRMED

From the Chicago Tribune:

A Republican source confirms that John McCain has chosen Alaska Governor Sarah Palin to be his running mate. Campaign officials, however, remain mum this morning.

(Hat tip: Rodrigo, via a Twitter search for "Palin.")

P.S. The same search also turned up this: "Palin's staff just said...they don't know where Palin is...LOL!" That would contradict the earlier report to the contrary, and vindicate FlyOnTheWall's guess about the reliability of said report.

UPDATE: CNBC says it's Palin. Drudge linking.

UPDATE, 10:38 AM: CNN Breaking News: It's Palin!
