As Think Progress notes:
On his campaign website, Harris explains, “[a]s a physician, I know that our health insurance system is in need of repair. However, the answer to the ever-rising cost of insurance is not the expansion of government-run or government-mandated insurance but, instead, common-sense market based solutions that ensure decisions are made by patients and their doctors.”And yes, he was railing against "government-run healthcare," which he's now embracing. But that's because he's assuming, correctly, that Congressmen healthcare is great and doesn't let government bureaucrats get between patients and doctors. And the reason he was against "Obamacare" is because he somehow imagines it does.
During an event at the Cecil County Patriots Candidate Forum in February 2010, Harris claimed “there is no constitutionality mandated role for the federal government in health care,” and criticized Medicare and Medicaid. Turning his attention to the health care reform legislation then moving through Congress, he described the public option as “a terrible idea,” adding, “you can’t have government-run health care, it’s just not right.” In July of 2009, Harris also appeared on Fox Business and warned viewers that if health reform passes, “we’ll look like Canada and England.” “Americans are not going to tolerate a bureaucrat making a decision for their families medicare care,” he said.
And so the problem here isn't that he doesn't want people to have healthcare, because he obviously does. The problem is that he's too ignorant to even know what it is that he's attacking. He's been told that government bureaucrats will be making medical decisions for us and he's simply repeating what he's been told. And while I'm sure he feels like a complete idiot at this point for having bitched about not getting his government healthcare soon enough, it's quite unlikely he'll understand why. He knows that he wants good healthcare for everyone, he just doesn't know that Obama is getting it for us.
My only hope in all this is that when Republicans finally turn to look at the healthcare law to see which parts they want to repeal, they'll finally see what it is and quit attacking it. Hell, if they just focus all their energies looking to repeal the part where government bureaucrats make medical decisions, maybe they'll never have time for anything else. We can only hope.
