Two-thirds of Democrats want her to stay in the race if she loses -- loses -- either Ohio or Texas and wins either Ohio or Texas.
The Obama campaign's Bill Burton just e-mailed a paragraph's response to reporters:
The Clinton campaign said this race was all about delegates and that they would be tied or ahead by morning. But despite the 20-point lead in Ohio and Texas that Senator Clinton had just two weeks ago, we will still be well ahead in delegates tonight and they will have failed at achieving their plainly stated goals. They have floated proposal after proposal to try to subvert the will of Democratic voters and retrospectively change the rules of the nominating process, but the bottom line is that it will still be virtually impossible for them to catch up in delegates after tonight.
