Cassidy, who has led previous failed efforts to repeal and replace the 2010 law, struck a bipartisan tone, saying discontent on the health care law could lead to changes both sides can agree on.

“I think I can say I’ve recognized those flaws for a little bit longer, and I would like to address it as well,” he continued. “Hopefully we come together on that.”

Health care proved to be a major motivation for Democratic voters in 2018, with candidates warning that electing and reelecting Republicans would result in more uninsured Americans.

The idea hasn't caught on with all Democrats on the campaign trail either.
