Thanks to the latest eyebrow-raising numbers out of California, the ObamacareSignups.net tally--including Medicaid expansion--now stands at 1,519,979.It's important to understand that sources and methodology for this sort of tracking is going to vary widely, depending on what exactly it is that you're trying to track (as well as the source, of course). In my case, yes, I'm including Medicaid expansion signups, because ultimately, what matters is people actually getting decent medical care at an affordable price.
In addition, I've chosen to include completed applications for healthcare plans, even if they haven't actually been enrolled yet. You could certainly argue that I shouldn't count it, but frankly, so many of the articles/sources I'm using fail to make that distinction either that I grew tired of trying to separate the wheat from the chaff.
