Being able to make great deals is what Donald Trump built his reputation on. He's using the tactics laid out in his 1987 bestselling book The Art of the Deal to win the battle over the Obamacare repeal bill.

On Thursday night, after the American Health Care Act (AHCA) vote had been delayed, the President gave Congress an ultimatum that if they didn't begin to vote on dismantling Obamacare by Friday, Trump would move on from the issue for the rest of the year, reported Fox News.

This comes directly out of The Art of the Deal playbook, where Trump wrote 30 years ago that the most important thing a businessman can do is know when to walk away from a deal.

House Leadership scrambled over the last 24 hours to make more concessions to both very conservative and moderate members of the Republican caucus. These include repealing essential benefits which will mostly likely be covered in the free market, keeping the 0.9 percent Medicare surtax for an additional six years, and adding $15 billion for maternity care, substance abuse, and mental health treatment.

The next few hours will determine whether Trump's ability to maneuver business deals can work with Congress and pass a bill that very few people actually like.
