Idaho's GOP governor backs Medicaid expansion

Idaho Gov. Butch Otter, a Republican, says his state should join the Affordable Care Act's Medicaid expansion. Otter appears in a new ad encouraging voters to support a ballot initiative next week that would adopt the expansion — a tool advocates turned to after elected officials resisted the expansion for years.

Why it matters: Medicaid expansion could be one of the biggest winners of the midterm elections. Three states — Idaho, Nebraska and Utah — will vote on ballot initiatives about whether to expand. If those measures pass, and Democrats win close gubernatorial races in large non-expansion states like Florida and Georgia, millions of uninsured people could end up getting Medicaid coverage.
