For now, the big news about Obamacare is the debacle of HealthCare.gov, the Web portal through which Americans are supposed to buy insurance on the new health care exchanges. For now, at least, HealthCare.gov isn’t working for many users.

It’s important to realize, however, that this botch has nothing to do with the law’s substance, and will get fixed. After all, a number of states have successfully opened their own exchanges, doing for their residents exactly what the federal system is supposed to do everywhere else. Connecticut’s exchange is working fine, as is Kentucky’s. New York, after some early problems, seems to be getting there. So, a bit more slowly, does California.

In other words, the technical problems, while infuriating — heads should roll — will not, in the end, be the big story. The real threat remains the effort of conservative groups to sabotage reform, especially by blocking the expansion of Medicaid. This effort relies heavily on lobbying, lavishly bankrolled by the usual suspects, including the omnipresent Koch brothers. But it’s not just money: the right has also rolled out some really lousy arguments.

And I don’t just mean lousy as in “bad”; I also mean it in the original sense, “infested with lice.”
