For years, Republicans have set their sights on dismantling Obamacare. Today, a vote on doing just that — and a new health care bill — didn't happen.

The American Health Care Act, also known as AHCA, keeps the most popular parts of Obamacare: Insurers can't deny coverage for pre-existing conditions and children can stay on their parents' insurance until the age of 26. It also keeps the concept of an online marketplace, where people can compare and buy insurance.

The new act eliminates individual mandates to buy health insurance and increased taxes on wealthy people and insurance companies.

Then-candidate Donald Trump ran on a platform of repealing and replacing Obamacare on Day 1. But, 63 days into Trump's presidency, the House of Representatives postponed the vote because the bill has the GOP split.

One faction, tea party Republicans, wants to simply repeal Obamacare. More moderate Republicans worry about millions of constituents losing insurance — and politically, losing their seats.

For what remains of the Affordable Care Act in the AHCA, some have dubbed "Obamacare Light" or "Obamacare 2.0."

Aubrey Jewett, a political science professor at the University of Central Florida, spoke to us about some of the ins and outs of the plan.

In order to pay for the plan, Jewett said, the working class will get less help buying insurance, and the plan sends less money to the states for Medicaid, which helps insure the poorest citizens.

The things that funded the Affordable Care Act, such as the penalty for not having health care and a higher tax on the wealthy, are going away.

"They're also going to allow insurance companies to charge seniors more for their health care," Jewett said.

Seniors need more care, which is more expensive. Under Obamacare, insurance companies charged seniors three times more than younger people. The new plan, according to Jewett, takes that to five times.

The Congressional Budget Office estimates the AHCA will reduce the federal deficit, saving more than $300 billion over the next decade.

Yet, even if the bill passes the House, there’s another hurdle: the Senate. When the bill hits that governmental body, Jewett said similar arguments will likely take place.
