Copy/paste from ABC News:

Nov. 10, 2006 — His party may have taken “a thumpin’,” in the words of President Bush, but ABC News has learned that Sen. John McCain, R-Ariz., and his political team have decided it’s full steam ahead for his 2008 presidential campaign though he has yet to make the final, official decision.

It’s now official (like we didn’t know it already was) that McCain is in. Really in essence, this isn’t big news, it’s simply a confirmation of the inevitable.
