CORRECTION: This article incorrectly said that Sen. Olympia J. Snowe (R-Maine) had "signaled she will back the health-care effort" in the Senate. In fact, while she voted for a version of the legislation in the Senate Finance Committee, she has not said whether she would vote for the Senate bill, which is still being finalized.
The 177 Republicans in the House of Representatives plan to unanimously oppose health-care legislation that would constitute the biggest expansion of insurance to Americans in decades, illustrating the huge divide that remains between the two parties on key issues and setting up a major debate in next year's elections.
The universal opposition to the health-care bill, which Congress could vote on as soon as Saturday, was long expected, but Republican wins in the Virginia and New Jersey gubernatorial races on Tuesday further emboldened the GOP in its stance. If all Republicans vote no on the health reform bill, it would mean not a single Republican up for election next year in the House or the Senate has backed the two biggest initiatives of President Obama's first year in office -- the $787 billion economic stimulus plan and the health-care legislation.
