WBRZ - Baton Rouge

Landmark health care legislation backed by President Barack Obama has passed its sternest Senate test, overcoming Republican delaying tactics on a 60-40 vote that all but assures its passage by Christmas.

The bill would extend coverage to more than 30 million Americans who now lack it, while banning insurance company practices such as denial of benefits on the basis of pre-existing medical conditions.

Under Senate rules, Democrats need 60 votes on three separate occasions to pass the measure.

The House has already passed legislation, and attempts to work out a compromise are expected to begin in the days after Christmas.
