Senate Majority Leader Harry M. Reid announced that he will include a government-backed insurance plan in the chamber's healthcare reform legislation. Reid's decision was a reversal from two weeks ago, when he appeared inclined to set aside the idea in an attempt to avoid alienating party moderates. Doubts remain about whether he has the votes to guarantee passage, but he said he concluded that adding a public option was the best way of bringing the strongest possible bill to the Senate floor in November.
