WASHINGTON - The big economic stimulus package agreed to by House and Senate negotiators is on track for final action with a House vote possible Thursday or Friday.

The agreement on tax cuts and spending that started out at more than $800 billion has been pared to $789 billion.

President Barack Obama, who has campaigned energetically for the legislation, says it will “save or create more than 3.5 million jobs and get” the economy back on track.

Lower and middle-income taxpayers will see a bit more in their paychecks from a credit of $400 per individual and $800 per couple.

There’s also a subsidy for health care for the unemployed and billions for transportation projects and states.

Staff aides worked into the night drafting and double-checking the measure in hopes of officially unveiling it today.
