After a crazy 24 hours on Capitol Hill, the Republican plan to repeal and replace Obamacare appears to be dead for the time being.

President Trump is threatening to let the Affordable Care Act fail so Congress can start over.

How could the president make that happen? And what would it mean for Arizonans?

Just last month, 36-year-old community activist Ian Danley was posting Facebook pictures from his 2015 bout with cancer and urging friends to fight the Obamacare repeal.

"In June, I was feeling good and I had beat cancer twice," Danley said.

Then two weeks ago, his cancer returned.

"I got to head back into treatment," he said. "I didn't know I was fighting for myself."

Small business owner Kim Sertich has a different Obamacare story. She shared it with President Trump last spring.

"It's frustrating," she said. "People think we're making this up."

Sertich had to drop Obamacare when her premiums double. Now Trump is delivering a cold does of reality after Republicans failed to repeal and replace the Affordable Care Act.

"I've been saying that for a long time, let Obamacare fail, it'll be a lot easier," Trump said Tuesday. "And I think we're probably in that position where we'll just let Obamacare fail."

He has one very large hammer that could deliver a death blow to Obamacare.

The administration could cut off billions of dollars in subsidies to insurers. This would either force insurers to bail out the market or make premiums unaffordable.

In Arizona, eight of every 10 Obamacare enrollees depend on those subsidies to buy health insurance.

"Maybe it makes everybody rethink their position and there is a sense of urgency," Sertich said.

Danley agreed Obamacare isn't perfect but without it, he couldn't afford the year of chemo that lies ahead.

I'm in trouble," he said. "This is it. I need this."

When President Trump says he'll let Obamacare die, there are ways he can make that happen.
