For months, as the inherent design flaws of President Obama's health care law began becoming apparent, the program's defenders had settled on a new argument to deflect criticisms.

Much of the problem, they argued, was a result of Republican obstructionism, which they said was evidenced by the fact that the program was working out a lot better in states where the governments were being more cooperative. That argument just got significantly harder to make.

Washington, D.C., was an early and enthusiastic adopter of Obamacare, yet on Wednesday, it announced a major delay.

According to the D.C. Health Benefit Exchange Authority, its exchange would not be “deploying the function that makes new Medicaid eligibility determinations and calculates tax credits for purchase of private insurance due to a high error rate.”

In other words, instead of signing onto a website like Orbitz or Expedia to purchase insurance – with the site immediately estimating the level of subsidies to which individuals are entitled – participants will now have to submit an application that will then be reviewed by experts who will make determinations in early November.

Funny enough, the press release announcing the delay was titled "DC Health Link Will Open for Business on October 1."

The Wall Street Journal also reported:

Two other states that are running their own exchanges — Colorado and Oregon — have also announced delays.

Colorado officials said this week that people who want to apply for a tax credit will have to work through the state's customer-service center for at least the month of October.

Last month, Oregon said it wouldn't allow individuals to enroll online on Oct. 1 until glitches with the system are worked out.

Colorado, Oregon and D.C. are all pro-Obamacare, and yet they are all running into major implementation problems. So much for blaming Republican obstruction.
