Democrats are trying to ban low-cost health insurance that covers less than ObamaCare. They claim they’re protecting the public from what Sen. Chuck Schumer calls “junk insurance.” Don’t believe it.

In truth, they’re sabotaging middle-class consumers who’ve been priced out of ObamaCare.

The Affordable Care Act requires all health plans to cover 10 categories of medical care that Washington politicians deem “essential.” Everything from maternity (even if you’re in your 50s) to substance-abuse treatment. It’s like passing a law saying the only car you can buy is a fully loaded SUV. Some people just need wheels.

If you need health insurance, basic coverage without the costly extras sure beats being uninsured.

Trouble is, ObamaCare is a budget buster. Premiums for 2019 will be about triple what they were six years ago. Not a problem for buyers who get subsidized by Uncle Sam. But it’s a big problem if you earn more than $48,560 individually or $65,840 as a couple, and can’t get a subsidy.

One out of every five of these unsubsidized ObamaCare customers dropped their insurance last year and went uncovered, a trend predicted to worsen this year. Not that Schumer and the rest of Congress feel the pain. They get their own sweetheart deal.

Meanwhile, the middle class is becoming the new uninsured. Somebody needs to remind the Democratic Party that poor lives matter but so do middle-class lives.

Enter Trump. On Aug. 1, the administration announced regulatory changes that’ll allow sticker-shocked consumers to buy “short term” health plans without costly extras like newborn care and pediatric dental coverage that are mandatory (even for single guys) in ObamaCare plans. The short-term plans, which can last three years, will cost less than half what ObamaCare costs, in some cases only a quarter as much. About 600,000 consumers are expected to snap up these lower-cost plans in the first year, 2 million by 2023.

Disregard panicky predictions that consumers who don’t read the fine print will get a rude awakening. Trump’s regulations require exclusions to be spelled out in huge typeface no one can miss. Buyers will know what they’re not getting before they sign up.

How about Dem Sen. Tammy Baldwin’s rants about “junk” coverage? False. These low-cost plans will probably provide better access to hospital and doctors than ObamaCare plans, which often exclude specialty hospitals like MD Anderson Cancer Center in Texas and Memorial Sloan Kettering Cancer Center in New York, and include only doctors who take bargain-basement Medicaid fees.

Schumer tries to claim people with pre-existing conditions will be harmed because their ObamaCare premiums will rise as healthy people leave for less-costly alternatives. Sorry, senator, that’s another whopper. According to America’s Health Insurance Plans, the impact will be nearly imperceptible — under 2 percent.

Never mind hard facts. The Democratic Party is determined to outlaw low-cost alternatives to ObamaCare. They’re taking their battle to the states, which have the authority to ban these plans. Hawaii, Maryland, Connecticut and Washington state recently slammed the door on them. California is expected to follow. Consumers in most states will be free to buy low-cost options thanks to the Trump regulatory change, but not in these health-insurance gulags.

New York is the worst. Consumers here have the least freedom of choice and pay practically the highest premiums in the country. Even before ObamaCare, New York legislators pandered to interest groups by requiring that all plans cover a huge range of services.

Here’s how it works: Lobbyists get paid by chiropractors, infertility experts and other interest groups to push for mandatory coverage, and state legislators rake in contributions and accolades for going along. Everybody wins but John Q. Consumer, the middle-class chump who gets clobbered when he buys insurance.

Meanwhile, people who live in states with more health-insurance freedom will be saving thousands of dollars a year.
