Gulf oil spill voted top news story of 2010

The massive Gulf of Mexico oil spill, triggered by a deadly blast at a rig used by BP, was the top news story of 2010, followed by the divisive health care overhaul, according to The Associated Press' annual poll of editors and news directors.

The oil spill received 54 first-place votes out of 180 ballots cast for the top 10 stories. The health care bill was next, with 30 first-place votes. The U.S. election was third.

In fourth place was the U.S. economy, which had been voted the top story of 2009.

Here are 2010's top 10 stories, in order:

_GULF OIL DISASTER: The April 20 explosion at a BP-leased rig killed 11 workers and unleashed a deep-sea spill that ultimately spewed at least 170 million gallons of crude into the Gulf. Consequences included devastation for fishing and tourism industries, a huge and costly cleanup effort, a management change at BP, and creation of a $20 billion fund to pay for damages.

_HEALTH CARE OVERHAUL: After bitter political wrangling, President Barack Obama was able to sign into law one of his major campaign promises — a $1 trillion health care overhaul intended to expand coverage to more Americans. But Republicans used public misgivings about parts of the plan as a springboard for election gains, and the overhaul faced a welter of lawsuits challenging its constitutionality.
