I've posted a couple essays, here and here, about how Obamacare wasn't living up to what was promised.
However, today's news just elevated the issue from something of a general concern to something that will be hotly debate before the general election as an issue of immediate urgency.

Big health plans stung by losses in the first few years of the U.S. health law’s implementation are seeking hefty premium increases for individual plans sold through insurance exchanges in more than a dozen states.
The insurers’ proposed rates for individual coverage in states that have made their 2017 requests public largely bear out health plans’ grim predictions about their challenges under the health-care overhaul.
According to the insurers’ filings with regulators, large plans in states including New York, Pennsylvania and Georgia are seeking to raise rates by 20% or more.
In states such as Florida and Maryland, insurers are seeking to raise premiums by percentage averages that are markedly above 10%. Among those that have published so far, only in Vermont do big insurers’ requests fall below 10%.
Proposals still have to be approved by state regulators, and a full picture of final approved rates across the entire country likely won’t be known until shortly before HealthCare.gov and state equivalents reopen for the law’s fourth main enrollment window on Nov. 1.
Nonetheless, the proposed average increases that are available are a vivid indicator this year of how insurers are adapting to the 2010 Affordable Care Act’s transformation of the way health coverage is priced and sold in the U.S.

Much of this dramatic rise in premiums next year will come from the expiration in 2017 of two federal programs that protect insurance companies, known as risk corridors and reinsurance.
Premium increases of 20-30% are no laughing matter.

“Americans will continue to have affordable coverage options in 2017,” said Kevin Counihan, the CEO of HealthCare.gov. “Proposed rates aren’t what most consumers actually pay. The vast majority of consumers qualify for tax credits that reduce the cost of coverage below the sticker price, and people can shop around and find coverage that fits their needs and budget.”

That's sort of the issue here. Instead of subsidizing people's health care, Obamacare is taxpayer subsidizing private health insurance.
I have no problem at all usiing taxpayer money to get people health care. My problem is using that money for private shareholder profits.
And doing this comes with all sorts of ugly conditions.

ObamaCare is also bringing out corporate America’s worst crony-capitalist impulses. The health-insurance lobby has teamed up with trial lawyers to sue the federal government—through individual lawsuits and a $5 billion class action—for not following through on a sweetheart bailout deal buried in the law. This provision of ObamaCare would have required taxpayers to bail out insurers for losing money on the health-care exchanges.

Rising premiums is one problem. Sky-high deductibles is another.

Not only are bronze deductibles rising as high as $7,150 in 2017, from a maximum of $6,850 this year, but silver deductibles of $6,000 or more are becoming commonplace. In fact, Centene (CNC), one of the most aggressive exchange competitors when it comes to pricing, is planning to roll out a new silver plan with a $7,050 deductible next year under the Ambetter name — to go along with the $6,500-deductible silver plan it’s already offering.

This enormous deductibles are beginning to negatively effect public opinion.
