Which states are doing the best at signing up people for Obamacare? Business Insider has a state-by-state chart here showing the number of people who have completed the process 100 percent: they've actually chosen a specific plan and officially enrolled their families. But I figure a better measure of activity is the number of people who have completed an application and been confirmed eligible to purchase private insurance via the exchange. They still have the final enrollment step left, but they've obviously navigated everything successfully, which is a good measure of how smoothly things are rolling out.
The chart below shows the results for 49 states (there's no data for Massachusetts). States in red are running their own websites. States in blue are using the federal website. Vermont and Kentucky are way ahead of everyone else, and demonstrate how well the Obamacare rollout is doing in places where the website is working and the state government is doing a good job of marketing and operations. Raw data comes from today's HHS report.
