At this hour Indiana is still a nailbiter, (CBS called it for Hillary early, all the others see it as too close) but however it turns out it's a big win for Obama. Can't see how Hillary can recover from this though she may still contest the rest of the primaries. If you're interested, here are exit poll results from North Carolina and Indiana.
Preliminary comments: Obama may have gotten past Rev. Wright, Hillary's gas-tax-amnesty proposal didn't help her, and almost all the pundits got it wrong. More live comments here.
