Bill Clinton is apparently determined to make sure that President Obama’s health-care bill does not go the same way as his own effort in 1994. The former president is scheduled to address the Senate’s Democratic caucus on Tuesday. The caucus is showing signs of splintering over the abortion and public-option issues. Senator Ben Nelson of Nebraska said on Monday that he wanted to make sure no federal money is put toward abortion, and approved of the House’s measure to that end. "I want to make sure something comparable ... is in there," Nelson said.
