WASHINGTON (AP) — Democrats drove their election-year economic package toward Senate approval early Sunday, debating a measure with less ambition than President Joe Biden’s original domestic vision but that touches deep-rooted party dreams of slowing global warming, moderating pharmaceutical costs and taxing immense corporations. Debate began Saturday and by early Sunday morning, Democrats had swatted down over a dozen Republican amendments designed to torpedo the legislation or create campaign ads attacking Democratic senators. Despite unanimous GOP opposition, Democratic unity in the 50-50 chamber — buttressed by Vice President Kamala Harris’ tiebreaking vote — suggested the party was on track for a morale-boosting victory three months from elections when congressional control is at stake. “I think it’s gonna pass,” Biden told reporters as he left the White House early Sunday to go to Rehoboth Beach, Delaware, ending his COVID-19 isolation. The House seemed on track to provide final congressional approval when it returns briefly from summer recess on Friday.
