President Trump calls for Medicare changes during health care rally in The Villages

THE VILLAGES, Fla. — President Donald Trump on Thursday accused Democrats of an all-out attempt to "totally obliterate Medicare" and portrayed himself as the program’s defender as he took steps to expand Medicare’s private insurance option.

But no Democrat is proposing to take coverage or benefits away, a fact that undercuts Trump’s rhetoric, and Trump did not dwell on his own budget proposals for cuts in Medicare payments to hospitals and other providers.

Trump spoke at The Villages, a bustling community for adults in Central Florida, as he angrily defended himself against House Democrats’ impeachment inquiry. That part of the state overwhelmingly supported Trump in 2016.

Health care has emerged as a central issue for Democrats competing for their party’s 2020 presidential nomination. Much of the debate has centered on Sen. Bernie Sanders’ "Medicare for All" plan, which would cover everyone under a government-run plan and eliminate most private insurance.

"Medicare is under threat like never before," Trump said on Thursday. "Almost every major Democrat in Washington has backed a massive government health care takeover that would totally obliterate Medicare."

Far from "obliterating’" Medicare, Sanders says his plan would lower costs and provide new benefits, including coverage for long-term care.

Trump signed an executive order directing his administration to pursue changes to Medicare, which covers about 60 million seniors and disabled people. Much of what he wants to do is geared toward enhancing Medicare Advantage, the private insurance option picked by about one-third of seniors.

Medicare Advantage plans offer savings on premiums and an annual limit on out-of-pocket costs. These plans provide one-stop shopping, eliminating the need for separate supplemental insurance. Offered by major insurers, the plans also cover prescription drugs in most cases.

But there are trade-offs. People joining a Medicare Advantage plan generally must accept limits on their choice of hospitals and doctors as well as prior insurer approval for certain procedures. If they change their minds and decide to return to traditional Medicare, they’re not always guaranteed supplemental "Medigap" coverage, which is also private.

The president’s order is basically a to-do list for the Department of Health and Human Services that will require months of follow-up. Among the other priorities are an expansion of telemedicine and changes to avoid overpaying for procedures just because they get done in a hospital instead of a doctor’s office.

Health and Human Services Secretary Alex Azar said Trump’s order directs his department to examine whether its current policies and practices put traditional Medicare ahead of the private Medicare Advantage option. Some advocates for older people say that it’s the other way around and that the administration is trying to put private plans ahead.

The executive order does not involve a major overhaul of Medicare, which would require congressional approval.

So far the debate about Medicare for All has mainly been about its projected costs to the government, estimated at $30 trillion to $40 trillion over 10 years.

The Sanders plan would eliminate most private health insurance, including the Medicare Advantage option. Sanders, who unexpectedly underwent a heart procedure this week, says Medicare for All would nonetheless offer seniors broader benefits and lower costs.

Sanders’ style of single-payer health care has long been popular among liberals. But recent polling has shown that a majority of Democrats and independents who lean Democratic prefer expanding coverage by building on the Affordable Care Act, or the Obama-era health law. Trump is asking federal courts to overturn that law as unconstitutional, after a Republican-controlled Congress failed to repeal it his first year in office.

As a presidential candidate, Trump promised not to cut Medicare. As president, he has avoided calling for privatization of the program, raising the eligibility age beyond 65 or rolling back benefits.

But Trump’s latest budget proposed steep cuts in Medicare payments to hospitals and other service providers, prompting protests from the industry and accusations by Democrats that he was going back on his promises to seniors. The Medicare cuts went nowhere in Congress.

Florida Gov. Ron DeSantis is in attendance at Thursday's rally.

President Trump was originally scheduled to visit The Villages in early August, but had to postpone his trip because of back-to-back mass shootings in El Paso, Texas, and Dayton, Ohio.

The Villages, which spreads into parts of Sumter, Lake, and Marion Counties, has long been a heavily Republican community. President Trump overwhelmingly won among voters there during the 2016 election.
