AP reports that Democrats struggled to eliminate lingering complications standing in the way of House action this weekend on President Barack Obama's landmark health care overhaul. Their drive to make the nation's health care system more efficient and extend coverage to millions of uninsured Americans took on a growing sense of inevitability, picking up endorsements from a longtime liberal holdout and from a retired Roman Catholic bishop and nuns who broke with church leaders over the bill's abortion provisions. At the same time, last-minute snags related to costs delayed formal release of the legislation and an analysis from the Congressional Budget Office at least until Thursday. Democratic lawmakers had hoped to see those details last week. Since Democrats are promising 72 hours for lawmakers and the public to review the legislation once it's released, that would push a House vote on the bill until Sunday at the earliest — the same day Obama plans to leave for an overseas trip. Obama already has delayed the trip once so he can be present for the vote and help with the 11th-hour arm-twisting that inevitably will precede it.
