Demonstrators in support of U.S. President Barack Obama's health-care law, the Affordable Care Act (ACA), hold up 'ACA is Here to Stay' signs after the U.S. Supreme Court ruled 6-3 to save Obamacare tax subsidies outside the Supreme Court in Washington, D.C. June 25, 2015.

As Democrats and Republicans battle over which health care proposal should replace the Affordable Care Act, a majority of Americans say they don't think Congress should revamp the entire U.S. health care system, according to a new Kaiser Family Foundation poll.

Instead, voters would rather see lawmakers focus on a handful of changes, like protecting pre-existing conditions and tackling rising prescription costs and surprise medical bills.

Most Americans felt high drug costs are the most important issue for Congress to address, with 68% of those polled believing lawmakers should take targeted actions on rising prices. 64% believe Congress should focus on protecting pre-existing conditions, while half believe surprise medical bills should also be a "top priority."

"Everybody is concerned about drug prices because they're really feeling the pinch here," Robert Laszewski, president of Health Policy and Strategy Associates, said. He said the dramatic rise in drug costs over the last 10 years has made the issue a prime focus for Americans.

Though pre-existing conditions are protected now under the Affordable Care Act, also known as Obamacare, Laszewski said voters became worried after Republicans proposed to replace it in 2017. The legislation included a provision that under certain conditions would have undone Obamacare's ban on letting insurers charge more for people with those conditions. The bill failed to pass the Senate.

The recent poll shows Americans are more concerned about rising medical costs than access to health care, Ashley Kirzinger, associate director for the Public Opinion and Survey Research team at the Kaiser Family Foundation, said.

The health care debate has taken lawmakers by storm as the 2020 elections approach with both Democrats and Republicans promising to replace Obamacare. Though there have been some issues that have seen bipartisan support, like seeking to lower drug costs, lawmakers on both sides of the aisle have otherwise viciously attacked each other's attempts to reform the health care system.

President Donald Trump and Republicans have pledged to repeal Obamacare, though top Republicans have said the GOP will wait until Republicans regain control of the House of Representatives to unveil a replacement proposal. Republicans currently hold control of the Senate, but need 21 more seats in the House to win the majority.

Lawmakers believe Republicans' failed attempt to overturn Obamacare in 2017 led to Democrats taking control of the House in last year's midterm elections. The law is now in jeopardy once again after the Trump administration supported a lawsuit questioning its constitutionality.

More than half, 54%, of those polled by the Kaiser Family Foundation said they don't want to see the Supreme Court overturn Obamacare.

Meanwhile, some progressive Democrats like presidential hopeful Sen. Bernie Sanders are looking to replace Obamacare with "Medicare for All," which seeks to create a government-run health care plan that would cover every American. The proposal has support from fellow Democratic presidential candidates like Sens. Kamala Harris, D-Calif., Cory Booker, D-N.J., Elizabeth Warren, D-Mass., and Kirsten Gillibrand, D-N.Y., though Republicans and centrist Democrats have spoken against Sanders' legislation.

As lawmakers jockey over which overhaul of the health care system is best, Americans would rather Congress just fix the basics.

Less than a third of the people surveyed think a complete overhaul of the health care system should be a top priority in Congress, according to the poll. More than a third, 31%, think that the implementation of Medicare for All should be Congress' focus, while 27% think lawmakers should prioritize repealing Obamacare.

Though there has been talk from top politicians about completely redoing the health care system, lawmakers have also looked to fix the issues Americans want them to spotlight.

The Senate Finance Committee earlier this year held two hearings with the nation's top pharmaceutical companies and pharmacy benefit managers in an attempt to discover the source of rising drug costs. Protecting pre-existing conditions is also a bipartisan issue, with Democrats touting protections under Obamacare and Republicans offering an alternative protection plan in case the health care law is overturned.

Lawmakers have also introduced legislation to stop patients from getting hit with surprise medical bills and the White House promised to make the issue a priority for the Trump administration to tackle.

Laszewski said protecting pre-existing conditions, Medicaid expansion, providing subsidies for those who can't afford insurance and tackling rising drug costs are "crucially important" to Americans, but he noted that not every citizen is the same.

"Different people are impacted differently here," Laszewski said. "We can't just say all Americans are exactly alike."
