So by your logic we can't repeal Obamacare in full either, since the "shifting" back and forth is too damaging.
No, and I didn't say that.
What I said is that since Obamacare has been passed, expenditures and implementation already done, will raise the cost of all healthcare premiums as a whole, and all preexisting plans will cost more no matter what is done about the status of Obamacare..
