John Cornyn, the #2 Senate Republican, after meeting with some GOP governors, said no one who is currently on Medicaid will lose their coverage. How that squares with repealing Obamacare's Medicaid expansion along with most of the rest of the law is unclear.

When asked if pro-expansion state governors, including Ohio Gov. John Kasich, expressed concern over their constituents losing coverage, Cornyn said: "We're all concerned, but it ain't gonna happen."

What's next: That's a big promise, but it also seems like the only way out of the political mess repealing Medicaid expansion would create. Now the question is how to make good on that promise.
