I've once again relaunched my project from last fall to track Medicaid enrollment (both standard and expansion alike) on a monthly basis for every state dating back to the ACA being signed into law.
For the various enrollment data, I'm using data from Medicaid.gov's Medicaid Enrollment Data Collected Through MBES reports. Unfortunately, they've only published enrollment data through December 2020. In some states I've been able to get more recent enrollment data from state websites and other sources.
Today I'm presenting Idaho, which only actually implemented Medicaid expansion under the Affordable Care Act starting in January 2020...and thank God they did, because less than 2 months later everything hit the fan when the COVID pandemic hit the U.S., hard. In Idaho's case I've gotten data through April directly via the Idaho Dept. of Heath & Welfare.
