It means this week is a new narrative.
Nate at 538 did an astute connecting of the dots, with Drudge hyping a "comeback" in the tracking polls (a very select number of them, that is) as ground work for a possible McCain theme this week.
He wrote this up last night, and by this morning he was proved correct. McCain's theme of the week is to position himself as come-from-behind fighter, written off by the media, ready to shock everyone. Drudge was just helping to construct the narrative like the good little tool he is.
