The Republican War on Children's Health continues($). The House failed Wednesday to override President Bush's second veto of a children's health insurance bill, again confounding Democrats' plans to expand government-sponsored health coverage to include an additional four million low-income kids. The override failed 260-152, 15 votes short of the two-thirds majority required. Democrats wound up no closer to enacting their signature health policy proposal than they were in October, when their attempt to override Bush's first veto failed by 13 votes. In fact, Democrats lost ground since they passed the second bill Oct. 25 by 265-142, because three Democrats and two Republicans who supported that bill were absent for Wednesday's vote Roll call here. Rep. Jim Marshall (D-GA) was the lone Democratic 'nay' vote.
