Can Obama reasonably play it now? Despite what the polls say, the media has clearly built a sense that Obama should win today. Which means that the underdog, again despite the polls, is Clinton today. Nevertheless, here's Obama earlier:

"It is a very, very tight (race)," Obama told reporters, "You know, I mean we started 20 points behind in Texas and Ohio -- we closed the gap but you know whether it's going to be enough to actually win is going to depend on turn out." [snip]

"We know there's not going to be a huge shift in delegates one way or another just given the math," Obama said. "Which means that either way we will go to Mississippi or Wyoming next week."

Obama might be right about one thing. We may not have any answers after tonight.
