Obama's Week - Turning Point?

Interesting observation from Chuck Todd of NBC:

The turning point? So was this week a turning point in the presidential race? The Obama campaign certainly believes it was, and that this will be the moment that Obama grabs the lead for good. If McCain never catches up at this point, his campaign's actions this week (its blistering criticism of Obama and the media, the visuals it picked, its body language, its VP games) will get second-guessed for months. We know this was a significant week; the question is was it enough to erase the doubts voters have with Obama about his ability to be commander-in-chief? But just asking: Did this week tell us more about Obama or McCain? Watching McCain chasing the news cycle and his inability to not let Obama get under his skin -- and the campaign's -- suggests that they could be reactive from this day forward. Why, for instance, did the campaign insist on the equal treatment (see network interviews) this week and not simply attempt to create its own week of coverage from the nets? They were second fiddle all week, and seemed to almost demand being highlighted in that way.
