In last night’s debate in a key Senate race, Senate Minority Leader Mitch McConnell, R-Ky., and his Democratic opponent, Alison Lundergan Grimes, both obfuscated on questions about President Obama’s healthcare law, underscoring how the politics of the law is changing as it continues to get implemented.

Obamacare remains broadly unpopular, but amid all the horror stories, there are also people benefitting from its expansion of insurance coverage through the exchanges and Medicaid. This has complicated the repeal message that has been standard fare for Republicans for four years. This is particularly true in Kentucky, which is a conservative state with a large low-income population that is eligible for insurance benefits through the law.
