Washington HealthPlanFinder, Washington's Obamacare exchange, shut down after 2 plus hours operation Saturday morning. It was its first opening for new enrollees since last spring. It was making calculation errors on tax credits, so its maintainers shut it down.
They say it was best to close it because they learned last year that it is very hard to make corrections after enrollment (Why didn’t they fix that?), so it’s best to keep new people out until the fix is in place.
Sunday morning it is still closed. Who decided to not open it until after the election? There is no doubt about why they did.
