Do It Now Or Lose The Chance Forever!

On the GOP's propose repeal and replace Obamacare bill from an excellent editorial in today's Wall Street Journal:

The House bill is the only heath-care show in town. If conservatives join Democrats to defeat the measure, the result will be to preserve ObamaCare as is—and probably torpedo the rest of the GOP agenda including tax reform. Good luck running for re-election in 2018 with a record of failure.
The House proposal can be improved with amendments—and more work will be necessary in future years to make medicine more affordable, promote innovation, protect the most vulnerable and give patients more control of their health-care dollars. But the bill is a major down payment on a brighter health-care future. Republicans have a limited window for repeal and replace, and this is a once-in-a-generation opportunity. Democrats understand this, even if some conservatives don’t.
