Cynthia Lummis, a wealthy Republican House member from Wyoming, claims her husband passed away, thanks in part to Obamacare. Lummis cited the law as a major contributing factor to her husband's demise. Instead of blaming her husband, who could easily have afforded the test (who elected to skip the necessary diagnostic), she blames the best thing to happen to millions of low income Americans, Obamacare.
From Addicting Info:

Cynthia Lummis is actually among one of the richest members of Congress. In 2007-2008, Representative Lummis’ financial disclosure forms reported a net worth between $20 million and $75 million... Obamacare wasn’t designed for people who have $20-$75 million. It was passed so the rest of us, who are either self-employed or have no access to insurance, can afford health care. It’s not the fault of the law that Lummis’s husband chose not to get a potentially life saving test – if he chose not to get the test.

Steve Doocy was desperately trying to dramatize her 'poignant' moment during these ridiculous hearings based on a pompous MIT economics professor speaking candidly. Lummis would not take the bait and blame her husband's death entirely on the healthcare law. But she was willing to attribute a likely mistake in coverage to the passing of her husband. She believes men in general are easily dissuaded from seeking medical care, so any little glitch or problem will convince them to discount medical advice.

It's truly disingenuous to blame a death on a law which is reliant on the insurance marketplace, as we all know insurance companies aren't exactly cooperative and committed to the well-being of their customers. They are, like Republicans, only interested in financial gain and not human lives. Her husband's choices and consequences should not deny insurance to the millions of poor people who finally have access to medical care. But they sure as hell will try their best to perpetuate the Republican Cult of Death and take away as much as they can from poor and needy Americans.
