The race in the Texas primary is still very tight, but MSNBC has just called it for Clinton. Right now, with 75 percent of precincts reporting, Clinton leads by slightly more than 60,000 votes.
Not all is lost for Obama, however: Because of the complex formula Texas uses to divide delegates, it's possible for him to lose the popular count and still emerge from the state with a lead in delegates. The networks have not yet offered delegate projections.
Results from the Texas caucus, an entirely separate affair from the Texas primary, are also now streaming in. Obama is ahead in that race by more than 10 percentage points.
Update: Now CNN, too, has called the primary for Clinton.
