"It's a challenge for a Trump presidency," says Jack Hoadley, a research professor at Georgetown University's Health Policy Institute. "To get a true repeal and replace through, he needs 60 votes in the Senate." That's the minimum number of votes needed to block Senate action through filibuster.
"Repeal of the law is absolutely going to come up, and the only potential defense against that would be a Democratic filibuster — if Republicans even allow a filibuster," says Austin Frakt, a health economist who runs the blog The Incidental Economist.
But even if Trump can't repeal the Affordable Care Act in its entirety.... "He could change the details of how the marketplaces work," Hoadley says. "It's all worked out through regulation. You could just suspend the regulations."
