I'll admit it, I was thrown off the track by Obama's moves this week, but after better reflection, I'm rethinking my position.

That's exactly what threw me off--Obama's melding and changing line on several topics, most notably campaign finance and FISA. On the former, Obama came off looking arrogant, and on the latter he snubbed the liberal base by compromising on telecom immunity, a bete noir of the left.

Now I come to see his pragmatic and strategic moves to the center as smart and even principled. In terms of his campaign's overriding message this week, it has been "Obama can win." To put to rest, finally, Hillary's failed argument that only she could beat McCain. It's a step toward a robust fall campaign to come out saying "look at all the money and swing states we have."

Obama must be confident he has the party sewn up, and can go right at the general election campaign.
