Pennsylvania Gov. Ed Rendell is making an 11th-hour push to deliver on his promise to expand healthcare coverage for the uninsured. Seeking a compromise with Senate Republicans opposed to spending and taxing increases, Rendell has scaled back his original 2007 proposal, and dropped a request for a tobacco tax to help pay for it. The latest proposal would add 250,000 people to the state insurance program by 2012, but they would have more limited benefits than Rendell envisioned. The deal also would extend state subsidies to cover medical malpractice insurance for doctors.
