To suggest that the only solution is to scrap the ACA entirely and start over is narrow minded and is the reason why the GOP has been unable to move forward with any of their Healthcare plans.  The ONLY reason the GOP opposes the ACA is because Obama put it together.  None of the ideas in the ACA are original, and many of the key aspects of it came from Republicans like Romney.  

This thought process by the GOP that the ONLY solution is to scrap it completely is extremely short sited.  To suggest that the ACA is unworkable for some reason makes no sense, and in fact goes against how most things work in government.  Very rarely if something isnt working exactly like how its supposed to do we scrap it all together.  We introduce legislation that helps fix the specific issues.  

Thats how adults govern.  And why the GOP has not been able to accomplish anything since Trump took office.
