It should be axiomatic among Republicans that Obamacare must be repealed and replaced during the current Congress. The last opportunity to do so appears to be the Graham-Cassidy bill. That being so, it must pass, and it must be improved before it passes. Specifically, the bill’s experiments in actual health insurance markets, need to be made more robust.

It is only by passing a repeal and replace bill that Republican politicians can avoid breaking the cardinal promise they have made to voters for the past four election cycles. It was the central rallying cry of John Boehner’s successful retaking of the House in 2010. Running Mitt Romney, author of Obamacare’s state-level prototype in 2012, proved a Republican mistake that helped save Obama. Campaigning against Obamacare helped Republicans take the Senate in 2014. Repealing Obamacare was the only policy agreed upon by all 17 GOP presidential candidates in the 2016 campaign.
